Uncleanness

Uncleanness in scripture is a layered category. At its base it is a ritual condition that bars a person from the sanctuary and the holy meal; above that it is a moral condition of the heart, the speech, and the body; and above both, it is the state from which Yahweh, and finally the blood of Christ, work to cleanse a people for himself. The same vocabulary — unclean, defile, wash, purify — runs through every layer.

The Levitical Definition

The priestly law distinguishes the unclean from the clean and lays out, case by case, what makes a person ritually unfit. Skin disease is the paradigm: "the priest will look at the plague in the skin of the flesh: and if the hair in the plague has turned white, and the appearance of the plague is deeper than the skin of his flesh, it is the plague of leprosy; and the priest will look at him, and pronounce him unclean" (Lev 13:3). Raw flesh, a deep lesion, a spreading bright spot — each receives the verdict "unclean" (Lev 13:14, Lev 13:25, Lev 13:36). The leper himself is told to publish his condition: "his clothes will be rent, and the hair of his head will go loose, and he will cover his upper lip, and will cry, Unclean, unclean" (Lev 13:45). The same applies to a contaminated house: anyone who enters it while shut up "will be unclean until the evening" (Lev 14:46).

Bodily discharges form a second class. "This will be his uncleanness in his discharge: whether his flesh runs his discharge, or his flesh be stopped from his discharge, he is unclean" (Lev 15:3). Touch transmits it: anyone whom the man with a discharge touches, "without having rinsed his hands in water, he will wash his clothes, and bathe himself in water, and be unclean until the evening" (Lev 15:11).

A third class is contact with the unclean itself. A soul who touches the carcass of an unclean beast or creeping thing, or "the uncleanness of man," contracts guilt as soon as he knows it (Lev 5:2-3). Eating from the peace-offerings while in a state of uncleanness is a capital matter: "the soul who eats of the flesh of the sacrifice of peace-offerings, that pertain to Yahweh, having his uncleanness on him, that soul will be cut off from his people" (Lev 7:20). The same applies to anyone who touches "any unclean thing, the uncleanness of man, or unclean beast, or any unclean reptile, and eat[s] of the flesh of the sacrifice of peace-offerings" (Lev 7:21). Eating an animal that has died of itself or been torn requires washing, bathing, and waiting until evening (Lev 17:15). For priests the standard is stricter: a leper or a man with a discharge in Aaron's line "will not eat of the holy things, until he is clean," and any contact "with the dead, or a man who has an emission of semen," or "any creeping thing, by which he may be made unclean," disqualifies him until evening and washing (Lev 22:4-6).

The food laws sit alongside these rules. The whole of Leviticus 11 and Deuteronomy 14 are aimed "to make a distinction between the unclean and the clean, and between the living thing that may be eaten and the living thing that may not be eaten" (Lev 11:46-47); the corresponding command in Deuteronomy is blunt: "You will not eat any disgusting thing" (Deut 14:3). Israel is not to defile itself with creeping things, "neither will you⁺ become unclean with them, so that you⁺ should be defiled by them" (Lev 11:43).

Why It Matters: The Tabernacle in the Camp

The driving concern is not hygiene but proximity. Yahweh's tent stands in the middle of the camp, and the holy things will not coexist with uncleanness. "Thus you⁺ will separate the sons of Israel from their uncleanness, that they will not die in their uncleanness, when they defile my tabernacle that is in the midst of them" (Lev 15:31). The Day of Atonement is therefore an annual cleansing of the place itself: the high priest "will make atonement for the holy place, because of the uncleannesses of the sons of Israel, and because of their transgressions, even all their sins: and so he will do for the tent of meeting, that stays with them in the midst of their uncleannesses" (Lev 16:16).

Priests must keep that line clean in their own bodies and households. "None will defile himself for a soul among his relatives," Yahweh says of Aaron's sons (Lev 21:1). And the soul who touches such a person "will be unclean until the evening, and will not eat of the holy things, unless he bathe his flesh in water" (Lev 22:6). The Levites themselves, before entering service, undergo cleansing: "Take the Levites from among the sons of Israel, and cleanse them" (Num 8:6); "sprinkle the water of expiation on them, and let them cause a razor to pass over all their flesh, and let them wash their clothes, and cleanse themselves" (Num 8:7). At the bronze laver, when the priests "go into the tent of meeting, they will wash with water, that they will not die" (Ex 30:20); the consecration of Aaron and his sons begins at that same door, where Moses is to "wash them with water" (Ex 40:12). Solomon's temple keeps the same logic, with ten basins for the offerings and "the sea was for the priests to wash in" (2Ch 4:6).

The Rituals of Cleansing

The priestly system pairs each uncleanness with a path back. The cleansed leper "will wash his clothes, and shave off all his hair, and bathe himself in water; and he will be clean: and after that he will come into the camp, but will dwell outside his tent seven days" (Lev 14:8). A garment with the plague is washed and shut up another seven days (Lev 13:54). The man who lets the goat go for Azazel "will wash his clothes, and bathe his flesh in water, and afterward he will come into the camp" (Lev 16:26); the same for the one who burns the sin-offering bodies (Lev 16:28). The priest who handles the red heifer "will wash his clothes, and he will bathe his flesh in water, and afterward he will come into the camp, and the priest will be unclean until the evening" (Num 19:7). Soldiers returning from war wash on the seventh day (Num 31:24); their gear too — "every garment, and all that is made of skin, and all work of goats' [hair], and all things made of wood, you⁺ will purify yourselves" (Num 31:20). What touches the flesh of the most holy is itself made holy and is washed in a holy place (Lev 6:27).

The Pharisees in Mark inherit this water-and-touch grammar and extend it. "For the Pharisees, and all the Jews, except they wash their hands diligently, don't eat, holding the tradition of the elders" (Mark 7:3). Hebrews looks back on the whole apparatus and calls it "[being] only (with meats and drinks and diverse washings) carnal ordinances, imposed until a time of reformation" (Heb 9:10). At Passover the chief priests refuse to enter the Praetorium, "that they might not be defiled, but might eat the Passover" (John 18:28); the Passover crowd in John 11 goes up early "to purify themselves" (John 11:55). Hezekiah's Passover already exposed the limits of strict observance: many "had not cleansed themselves, yet they ate the Passover otherwise than it is written. For Hezekiah had prayed for them, saying, The good Yahweh pardon everyone" (2Ch 30:18).

Defilement Beyond the Body

The same vocabulary moves out from ritual into conduct. Sexual practice is the chief axis. "Don't defile yourselves in any of these things: for in all these the nations have been defiled which I am casting out from before you⁺" (Lev 18:24). The customs of those nations are why Yahweh "abhorred them" (Lev 20:23). A hanged criminal must be buried the same day "that you do not defile your land which Yahweh your God gives you for an inheritance" (Deut 21:23). Idolatry pollutes the sanctuary itself: Israel's chiefs and priests "trespassed very greatly after all the disgusting things of the nations; and they polluted the house of Yahweh" (2Ch 36:14). Ezra describes the land as "an unclean land through the uncleanness of the peoples of the lands, through their disgusting behaviors, which have filled it from one end to another with their filthiness" (Ezr 9:11). Ezekiel agrees: Israel is "defiled in [its] idols" (Eze 22:4), the priests have "profaned [Yahweh's] sanctuaries" (Eze 28:18), the temple gate has been used to "defile [Yahweh's] holy name by the disgusting behaviors that they have done" (Eze 43:8), foreigners have been brought in "to profane it" (Eze 44:7), and Zephaniah's priests "have profaned the sanctuary, they have done violence to the law" (Zeph 3:4).

The lips and hands are no exception. Isaiah indicts Jerusalem: "your⁺ hands are defiled with blood, and your⁺ fingers with iniquity; your⁺ lips have spoken lies, your⁺ tongue mutters wickedness" (Isa 59:3). The earth itself is "polluted under its inhabitants; because they have transgressed the laws, violated the statutes, broken the everlasting covenant" (Isa 24:5). James reads the tongue this way: "the tongue, which defiles the whole body, and sets on fire the wheel of nature, and is set on fire by hell" (Jas 3:6). Jesus locates the source inside the person: "all these evil things proceed from inside, and defile the man" (Mark 7:23). And Hebrews warns that bitterness, springing up, can "trouble [you⁺], and by it many be defiled" (Heb 12:15).

In the Maccabean crisis the two senses fuse. The Greek program forces Israel "to build altars, and temples, and idols, and to sacrifice swine's flesh, and unclean beasts" (1Ma 1:47), to "leave their sons uncircumcised, and let their souls be defiled with all uncleannesses, and detestable things" (1Ma 1:48), and "to defile the sanctuary, and the holy things" (1Ma 1:46). Mattathias laments that "our sanctuary, and our beauty, and our glory is laid waste, And the nations have defiled them" (1Ma 2:12); "your holies are trodden down, and are profaned, And your priests are in mourning, and are brought low" (1Ma 3:51). Judas leads the response: "let us go up now to cleanse the holy places and to repair them" (1Ma 4:36); they "cleansed the holy places, and took away the stones that had been defiled into an unclean place" (1Ma 4:43). Simon's later campaigns operate on the same logic: he "cleansed the houses in which there had been idols" (1Ma 13:47), "cast out of it all uncleanness" (1Ma 13:48), "cleansed the citadel from its defilements" (1Ma 13:50), and "took away all uncleanness out of [Gazara]" (1Ma 14:7); under his rule the nations who "defiled all places round about the sanctuary" are cleared out (1Ma 14:36).

Sexual Impurity

Within Torah's category of defilement, sexual misconduct gets its own vocabulary. Paul: "God delivered them up in the desires of their hearts to impurity, that their bodies should be shamed among themselves" (Rom 1:24); the men "leaving the natural use of the woman, became passionate with each other, men with men, shamefully having sex together" (Rom 1:27); believers had once "presented your⁺ members [as] slaves to impurity and to iniquity" (Rom 6:19). The Corinthian church is rebuked for whoring "as is not even among the Gentiles" (1Cor 5:1) and warned that every other sin is outside the body, but "he who goes whoring sins against his own body" (1Cor 6:18). "Stop being a whore" (1Cor 6:18); "let each have his own wife, and let each woman have her own husband" (1Cor 7:2); "Neither let us go whoring, as some of them went whoring, and 23,000 fell in one day" (1Cor 10:8). Paul mourns those who "didn't repent of the impurity and whoring and sexual depravity in which they participated" (2Cor 12:21). The Gentile pattern is "feeling no more pain, delivered themselves up to sexual depravity, to work all impurity with greed" (Eph 4:19); the saints are not even to let it "be named among you⁺" (Eph 5:3); they are to "Put to death therefore your⁺ members which are on the earth: whoring, impurity, immoral sexual passion, evil desire, and greed, which is idolatry" (Col 3:5). "God called us not for impurity, but in sanctification" (1Th 4:7); "abstain from whoring" (1Th 4:3), and "not by immoral sexual passion, even as the Gentiles who don't know God" (1Th 4:5).

The Hebrew witnesses agree. The Decalogue: "Neither will you commit adultery" (Deut 5:18). Job: "I made a covenant with my eyes; How then should I look at a virgin?" (Job 31:1). Proverbs: "why should you, my son, be ravished with a strange woman, And embrace the bosom of a foreigner?" (Prov 5:20); "Don't lust after her beauty in your heart" (Prov 6:25). Sirach: "Wine and women cause the heart to be lustful" (Sir 19:2); "Two types [of men] multiply sins, And a third brings wrath: A lustful soul burning like fire, Which is not quenched until it is consumed; A fornicator in the body of his flesh, For he does not cease until the fire consumes him" (Sir 23:16); "[And] the fornicator to whom all bread is sweet, For he will not leave off until he dies" (Sir 23:17); "Grace upon grace is a modest woman, And there is no weight [of gold] worth a self-controlled soul" (Sir 26:15). The Diognetus letter sums up the Christian sexual ethic with one line: "They eat together, but do not sleep together" (Gr 5:7). Marriage is "had in honor among all, and [let] the bed [be] undefiled: for whores and adulterers God will judge" (Heb 13:4). The 144,000 in Revelation "were not defiled with women; for they are virgins" (Rev 14:4). Pastors are to flee "youthful lusts" (2Tim 2:22) and the wives of Titus 2 are "[to be] sober-minded, chaste" (Titus 2:5). Peter targets those who "walk after the flesh in the desire of defilement, and despise dominion" (2Pet 2:10), and Jude reaches for Sodom and Gomorrah, who "committed sexual depravity and homosexuality" (Jude 1:7).

The Limits of Washing

The prophets and the wisdom writers press past the rite to its inadequacy. Sirach asks the question directly: "What can be made clean from an unclean thing? And how can that which is true come from a lie?" (Sir 34:4); "He who washes after [contact with] a dead body, and touches it again, What profit does he have by his washing?" (Sir 34:30). Pilate stages the gesture in vain at his trial — Deuteronomy's elders "wash their hands over the heifer whose neck was broken" (Deut 21:6) and the psalmist says "I will wash my hands in innocence: So I will go about your altar, O Yahweh" (Ps 26:6) — but Asaph's confession is that "in vain I have cleansed my heart, And washed my hands in innocence" (Ps 73:13). The basin is not the heart.

David's psalm names the deeper need. "Have mercy on me, O God, according to your loving-kindness" (Ps 51:1); "Wash me thoroughly from my iniquity, And cleanse me from my sin" (Ps 51:2); "I know my transgressions; And my sin is ever before me" (Ps 51:3); "Against you, you only, I have sinned" (Ps 51:4); "I was brought forth in iniquity; And in sin did my mother conceive me" (Ps 51:5); "you desire truth in the inward parts" (Ps 51:6); "Purify me with hyssop, and I will be clean: Wash me, and I will be whiter than snow" (Ps 51:7); "Make me to hear joy and gladness" (Ps 51:8); "Hide your face from my sins, And blot out all my iniquities" (Ps 51:9); "Create in me a clean heart, O God; And renew a right spirit inside me" (Ps 51:10); "Don't cast me away from your presence; And don't take your Holy Spirit from me" (Ps 51:11); "Restore to me the joy of your salvation" (Ps 51:12); "Then I will teach transgressors your ways" (Ps 51:13); "Deliver me from bloodguiltiness" (Ps 51:14); "O Lord, open my lips" (Ps 51:15); "you do not delight in sacrifice; or else I would give it" (Ps 51:16); "The sacrifices of God are a broken spirit: A broken and a contrite heart, O God, you will not despise" (Ps 51:17); "Do good in your good pleasure to Zion" (Ps 51:18); "Then you will delight in the sacrifices of righteousness" (Ps 51:19). The same plea returns elsewhere: "Iniquities prevail against me: As for our transgressions, you will forgive them" (Ps 65:3); "deliver us, and forgive our sins, for your name's sake" (Ps 79:9); "Who can discern [his] errors? Acquit me from hidden [faults]" (Ps 19:12).

Isaiah lays the demand on Israel: "Wash yourselves, make yourselves clean; put away the evil of your⁺ doings from before my [Speech]; cease to do evil" (Isa 1:16); and pairs it with promise: "though your⁺ sins be as scarlet, they will be as white as snow" (Isa 1:18). The same pairing comes when the seraph touches Isaiah's mouth: "your iniquity is taken away, and your sin forgiven" (Isa 6:7). Jeremiah: "O Jerusalem, wash your heart from wickedness, that you may be saved. How long will your evil thoughts lodge inside you?" (Jer 4:14). Sirach: "Turn from iniquity, and purify your hands; And from all transgressions cleanse your heart" (Sir 38:10). And the Psalter notes the universal failure: "Every one of them has gone back; they have together become filthy; There is none who does good, no, not one" (Ps 53:3).

The Promise of a Real Cleansing

Against that failure the prophets place a promise. Ezekiel: "I will sprinkle clean water on you⁺, and you⁺ will be clean: from all your⁺ filthiness, and from all your⁺ idols, I will cleanse you⁺" (Eze 36:25). Zechariah: "in that day there will be a fountain opened to the house of David and to the inhabitants of Jerusalem, for sin and for uncleanness" (Zech 13:1). Malachi: "he will sit as a refiner and purifier of silver, and he will purify the sons of Levi, and refine them as gold and silver; and they will offer to Yahweh offerings in righteousness" (Mal 3:3). Zechariah 3 enacts it: the angel commands those who stand before Joshua, "Take the filthy garments from off him… Look, I have caused your iniquity to pass from you, and I will clothe you with rich apparel" (Zech 3:4).

The New Testament reads its own cleansing through that promise. Jesus tells the disciples, "Already you⁺ are clean because of the word which I have spoken to you⁺" (John 15:3). Paul's reckoning of the Corinthians' past — "such were some of you⁺: but you⁺ were washed, but you⁺ were sanctified, but you⁺ were justified in the name of the Lord Jesus Christ" (1Cor 6:11). The believer is to "cleanse ourselves from all defilement of flesh and spirit, perfecting holiness in the fear of God" (2Cor 7:1). Christ "loved the church, and delivered himself up for it; that he might sanctify it, having cleansed it by the washing of water with the word" (Eph 5:25-26). Salvation is "through the washing of regeneration and renewing of the Holy Spirit" (Titus 3:5). "If a man therefore purges himself from these, he will be a vessel to honor, sanctified" (2Tim 2:21).

The atoning blood replaces the ritual basin. "How much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, cleanse our conscience from dead works to serve the living God?" (Heb 9:14). "If we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus his Son cleanses us from all sin" (1Jn 1:7). Christ "loved us, and loosed us from our sins by his blood" (Rev 1:5). The redeemed of Revelation 7 "washed their robes, and made them white in the blood of the Lamb" (Rev 7:14). And the believer himself acts: "Draw near to God, and he will draw near to you⁺. Cleanse your⁺ hands, you⁺ sinners; and purify your⁺ hearts, you⁺ double-minded" (Jas 4:8). "Therefore putting away all filthiness and overflowing of wickedness, receive with meekness the implanted word, which is able to save your⁺ souls" (Jas 1:21). "Everyone who has this hope [set] on him purifies himself, even as he is pure" (1Jn 3:3). The disciples drawing near in worship are to come "with a true heart in fullness of faith, having our hearts sprinkled from an evil conscience, and having our body washed in pure water" (Heb 10:22). Old Testament images of hospitality and renewal — Abraham's guests' feet washed (Gen 18:4), Joseph's brothers' feet washed (Gen 43:24), Jacob's household putting away foreign gods and changing garments (Gen 35:2), Israel washing its garments at Sinai (Ex 19:14), Ruth washing and anointing (Ruth 3:3), David rising from mourning and washing before he worships (2Sam 12:20) — all anticipate that final cleansing.

In the end the priestly question — "What can be made clean from an unclean thing?" (Sir 34:4) — receives its answer not in stricter washing but in a new heart, a sprinkled conscience, and the blood of the Lamb.
