Consecration
Consecration is the act of setting a person, an object, or a place apart for Yahweh's exclusive use. The vocabulary of the practice — "sanctify," "anoint," "hallow," "separate" — runs from the ordination of Aaron at the door of the tent of meeting to the believer urged to present his body as a living sacrifice. The pattern is consistent: what Yahweh claims, men and women must in turn give, and the giving is not partial. Israel as a whole is told, "you⁺ will be holy to me: for I, Yahweh, am holy, and have set you⁺ apart from the peoples, that you⁺ should be mine" (Le 20:26). Every later figure for consecration draws on this primary one.
The Priestly Ordination
The first developed liturgy of consecration in the Pentateuch is the ordination of Aaron and his sons. Yahweh tells Moses, "And you bring near to you Aaron your brother, and his sons with him, from among the sons of Israel, that he may serve me in the priest's office" (Ex 28:1), and gives instructions for "holy garments for Aaron your brother, for glory and for beauty" (Ex 28:2), garments made by craftsmen "to sanctify him, that he may serve me in the priest's office" (Ex 28:3). The rite itself is laid out the next chapter: the bull and two rams brought to the door of the tent, the washing with water, the vesting in coat and ephod and breastplate, the turban and holy crown, and "the anointing oil" poured upon the head (Ex 29:1-7). The closing line states the verb plainly: "and you will consecrate Aaron and his sons" (Ex 29:9).
The narrative execution in Leviticus repeats the ritual without abridgement. Moses takes the anointing oil and "anointed the tabernacle and all that was in it, and sanctified them," sprinkles the altar seven times "to sanctify them," and pours the oil on Aaron's head "to sanctify him" (Le 8:10-12). Sirach's hymn to the fathers preserves the same picture: "Moses consecrated him, And anointed him with the holy oil; And it became for him an eternal covenant" (Sir 45:15), with Aaron exalted "by a perpetual statute" (Sir 45:7) and clothed in "the perfection of adornment" (Sir 45:8). Ben Sira frames the priesthood as a covenantal vocation, not a courtly office: "With all your soul, fear God. And sanctify his priests" (Sir 7:29). Even the priests, once ordained, must continue to consecrate themselves — "let the priests also, that come near to Yahweh, sanctify themselves, or else Yahweh will break forth on them" (Ex 19:22).
The Substitution of the Levites
The wider tribe of Levi is set apart by a different mechanism: not anointing, but substitution. Yahweh's claim on the firstborn is the framework. "Sanctify to me all the firstborn, whatever opens the womb among the sons of Israel, both of man and of beast: it is mine" (Ex 13:2). The claim is grounded in the tenth plague: "on the day that I struck all the firstborn in the land of Egypt I sanctified them for myself" (Nu 8:17). The Levites are then taken in lieu of every firstborn son: "Thus you will separate the Levites from among the sons of Israel; and the Levites will be mine" (Nu 8:14), "instead of all that opens the womb, even the firstborn of all the sons of Israel, I have taken them to me" (Nu 8:16). The remaining firstborn of men are redeemed with money — "the firstborn of man you will surely redeem" (Nu 18:15) — and the firstlings of beasts are sacrificed. Every firstborn in Israel is consequently a consecrated thing, marked either by service or by ransom.
The Nazirite Vow
The Nazirite vow is consecration extended to laity. "When either man or woman will make a special vow, the vow of a Nazirite, to separate himself to Yahweh," he abstains from wine and any product of the grapevine, leaves his hair uncut "until the days be fulfilled," and avoids contact with the dead, "because his separation to God is on his head" (Nu 6:2-7). The summary verse states the result: "All the days of his separation he is holy to Yahweh" (Nu 6:8). The vow has a fixed terminus: when the days are fulfilled the Nazirite is brought to the door of the tent, presents burnt-offering, sin-offering, and peace-offerings, shaves his head, and burns the hair on the fire under the peace-offerings (Nu 6:13-18). Hannah's promise concerning Samuel reads as a Nazirite-shaped dedication: "if you will indeed look at the affliction of your slave... I will give him to Yahweh all the days of his life, and no razor will come upon his head" (1 Sa 1:11). After his birth she carries through: "I prayed for this lad; and Yahweh has given me my petition... therefore I also have granted him to Yahweh; as long as he lives he is granted to Yahweh" (1 Sa 1:27-28).
Sanctuary, Altar, and Vessel
The places and instruments of worship are consecrated alongside their officiants. At Sinai, Moses anoints "the tabernacle, and all that is in it, and will hallow it, and all its furniture" (Ex 40:9), then anoints "the altar of burnt-offering, and all its vessels, and sanctify the altar: and the altar will be most holy" (Ex 40:10), and finally Aaron and his sons in their holy garments (Ex 40:12-13). The altar stands at the centre. Sirach's portrait of the high priest Simeon on the day of atonement shows the altar in continuous, ordered use: "When he put on his glorious robes, And clothed himself in full splendor, When he went up to the altar of majesty" (Sir 50:11), "All the sons of Aaron in their glory, And the offering by fire to Yahweh in their hand" (Sir 50:13). Where altars stand profaned, they must be torn down and rebuilt; Judas Maccabaeus "chose priests without blemish, whose will was set on the law of God" (1 Ma 4:42), considered the defiled altar of burnt-offering, and pulled it down, the stones laid up "until there should come a prophet, and give answer concerning them" (1 Ma 4:46).
Dedication of the House
The dedication of a sanctuary is a corporate act of consecration. After Solomon completes the temple, "the king, and all Israel with him, offered sacrifice before Yahweh," and "Solomon offered for the sacrifice of peace-offerings, which he offered to Yahweh, two and twenty thousand oxen, and a hundred and twenty thousand sheep. So the king and all the sons of Israel dedicated the house of Yahweh" (1 Ki 8:62-63). The same verb attaches to the rebuilt second-temple altar after its desecration. Once a new altar has been built according to the former pattern, "they kept the dedication of the altar eight days, and they offered burnt-offerings with joy, and sacrifices of salvation, and of praise" (1 Ma 4:56), and the assembly decreed "that the day of the dedication of the altar should be kept in its season from year to year for eight days, from the five and twentieth day of the month of Kislev, with joy and gladness" (1 Ma 4:59). That festival is the one Jesus is observed attending: "Then came the feast of the dedication at Jerusalem. It was winter" (Jn 10:22).
Even outside ritual settings, the language of dedication can attach to a private gift offered up to Yahweh. When the three mighty men break through the Philistine camp to bring David water from the well at Bethlehem, David refuses to drink it but "poured it out to Yahweh" (2 Sa 23:16). Jacob's vow at Bethel is the conditional form of personal dedication: "If [the Speech of] God will be with me... then this stone, which I have set up for a pillar, will be God's house. And of all that you will give me I will surely give the tenth to you" (Ge 28:20-22).
Israel as a Holy Nation
Beyond the priestly caste, the whole nation is brought under the language of consecration. At Sinai Yahweh declares, "if you⁺ will obey [my Speech] indeed, and keep my covenant, then you⁺ will be my own possession from among all peoples... and you⁺ will be to me a kingdom of priests, and a holy nation" (Ex 19:5-6). The same calling reappears in Isaiah's restoration oracle: "But you⁺ will be named the priests of Yahweh; men will call you⁺ the ministers of our God" (Is 61:6). Communal consecration also functions as preparation for divine action. Before the crossing of the Jordan, Joshua tells the people, "Sanctify yourselves; for tomorrow Yahweh will do wonders among you⁺" (Jos 3:5). Sirach intercedes in the same idiom: "As you have sanctified yourself in us before their eyes, So sanctify yourself in them before our eyes" (Sir 36:4).
Christ as Sanctifier
In the New Testament the verb "sanctify" no longer attaches primarily to oil and altar but to the work of Christ. Jesus prays, "Sanctify them in the truth: your speech is truth," and grounds his prayer in self-consecration: "And for their sakes I sanctify myself, that they themselves also may be sanctified in truth" (Jn 17:17, 19). Hebrews makes the cross the once-for-all consecration: "By whose will, we have been sanctified through the offering of the body of Jesus Christ once for all" (He 10:10), and "Therefore Jesus also, that he might sanctify the people through his own blood, suffered outside the gate" (He 13:12).
Present Your Bodies
Paul completes the figure by transferring the temple vocabulary to the believer. "I urge you⁺ therefore, brothers, by the mercies of God, to present your⁺ bodies, a living sacrifice, holy, acceptable to God, [which is] your⁺ spiritual service" (Ro 12:1). The same verb, present, is used negatively a few chapters earlier — "neither present your⁺ members to sin [as] instruments of unrighteousness; but present yourselves to God, as alive from the dead, and your⁺ members [as] instruments of righteousness to God" (Ro 6:13) — and is then folded back into the consecration vocabulary: "even so now present your⁺ members [as] slaves to righteousness to sanctification" (Ro 6:19). Paul's own apostolic ministry he describes as a kind of priestly liturgy: "that I should be a minister of Christ Jesus to the Gentiles, ministering the good [news] of God, that the offering up of the Gentiles might be made acceptable" (Ro 15:16). The Macedonian model of self-giving is described in the same shape: "first they gave their own selves to the Lord, and to us through the will of God" (2 Co 8:5). Sanctification is not a peripheral demand. "For this is the will of God, [even] your⁺ sanctification" (1 Th 4:3).
The Spiritual Temple and Spiritual Priesthood
The corporate body of believers is then itself the temple. "Don't you⁺ know that you⁺ are a temple of God, and [that] the Spirit of God dwells in you⁺? If any man destroys the temple of God, him will God destroy; for the temple of God is holy, and such are you⁺" (1 Co 3:16-17). The same is said of the body of the individual believer: "your⁺ body is a temple of the Holy Spirit who is in you⁺, whom you⁺ have from God? And you⁺ are not your⁺ own; for you⁺ were bought with a price: glorify God therefore in your⁺ body" (1 Co 6:19-20). The community-as-temple language carries the old promise of presence: "we are a temple of the living God; even as God said, I will dwell in them, and walk in them" (2 Co 6:16). Peter combines temple and priesthood in a single image: "you⁺ also, as living stones, are built up a spiritual house, to be a holy priesthood, to offer up spiritual sacrifices, acceptable to God through Jesus Christ" (1 Pe 2:5). The sacrifices are not abolished, only re-defined: "Through him then let us offer up a sacrifice of praise to God continually, that is, the fruit of lips which make confession to his name. But to do good and to communicate do not forget: for with such sacrifices God is well pleased" (He 13:15-16). Behind it all stands the principle that the contrite heart was always the primary offering: "The sacrifices of God are a broken spirit: A broken and a contrite heart, O God, you will not despise" (Ps 51:17).
