Tongue
The tongue moves through scripture as a created organ, as the bearer of language across the nations, as a fire that wrecks or heals, as the instrument of confession before God, and as a charismatic gift in the assembly. The same word names a piece of flesh, a national speech, and the act that puts a person on one side or the other of belief. The arc runs from one language at Babel to many tongues scattered, and from many tongues to a single confession that the Lord is Jesus Christ.
Formed by God, Numbered Among the Senses
The tongue is given as part of the equipment for understanding. Sirach places it alongside eyes, ears, and a heart: "He formed for them tongue, and eyes, and ears, And gave them a heart to understand," (Sir 17:7). The organ is for sense-making. Speech is its native work — "The beginning of every action is speech, And before every act there is consideration," (Sir 37:16) — and the tongue's reach across the moral field is total: "Good and evil, life and death; But the tongue rules over them altogether," (Sir 37:18).
One Language, Many Tongues — Babel and the Nations
In the Table of Nations the spread of peoples is sorted by speech: "Of these were the isles of the nations divided in their lands, every one after his tongue, after their families, in their nations" (Gen 10:5), and again, "These are the sons of Ham, after their families, after their tongues, in their lands, in their nations" (Gen 10:20). Multiplicity of tongues is the world's organizing pattern.
The break that produced this pattern is the Babel narrative. "And the whole earth was of one language and of one speech" (Gen 11:1). Building a city and tower so as not to be scattered, the people are answered by Yahweh's coming down: "Look, they are one people, and they all have one language; and this is what they begin to do: and now nothing will be withheld from them, which they purpose to do. Come, let us go down, and there confound their language, that they may not understand one another's speech" (Gen 11:6-7). "So [the Speech of] Yahweh scattered them abroad from there on the face of all the earth: and they left off building the city" (Gen 11:8). The naming summarizes the whole: "Therefore the name of it was called Babel; because there Yahweh confounded the language of all the earth: and from there Yahweh scattered them abroad on the face of all the earth" (Gen 11:9).
After Babel, particular languages mark national identity. At the wall of Jerusalem the envoys ask Rabshakeh to switch registers: "Speak, I pray you, to your slaves in the Aramaic language; for we understand it: and don't speak with us in the Jews' language, in the ears of the people who are on the wall" (2Ki 18:26). In Nehemiah's mixed-marriage purge the loss of Hebrew is itself the offense: "and their sons spoke half in the speech of Ashdod, and could not speak in the Jews' language, but according to the language of each people" (Ne 13:24). The Fourth Gospel notes Hebrew place-names — "Now there is in Jerusalem by the sheep [gate] a pool, which is called in Hebrew Bethzatha, having five porches" (Jn 5:2) — and at the cross the title is trilingual: "it was written in Hebrew, [and] in Latin, [and] in Greek" (Jn 19:20).
The Babel Arc Reversed: Every Tongue Gathered
The scattering does not have the last word. Isaiah projects an end-time gathering of "all nations and tongues" before God's glory: "[the time] comes that I will gather all nations and tongues; and they will come, and will see my glory" (Isa 66:18). Revelation answers in the same idiom: "I looked, and saw a great multitude, which no man could number, out of every nation and of [all] tribes and peoples and tongues, standing before the throne and before the Lamb" (Re 7:9). The plurality that began at Babel ends gathered, not abolished.
The Tongue as Fire
For the wisdom literature and the New Testament epistles the tongue is the body's most dangerous organ. James names it bluntly: "And the tongue is a fire: the world of iniquity among our members is the tongue, which defiles the whole body" (Jas 3:6). The same writer calls the tongue's restraint the test of religion: "If any man thinks himself to be religious, while he doesn't bridle his tongue but deceives his heart, this man's religion is useless" (Jas 1:26). And: "For in many things we all stumble. If any doesn't stumble in word, the same is a perfect man, able to bridle the whole body also" (Jas 3:2).
Sirach develops the theme at length. The "third tongue" — the slanderer's — is treated as a weapon of mass destruction: "The third tongue has shaken many, And has dispersed them from nation to nation; Even strong cities it has pulled down, And overthrown the houses of great men" (Sir 28:14). "The third tongue has cast out brave women, And deprived them of their labors" (Sir 28:15). "The stroke of a whip makes a mark, But the stroke of a tongue breaks bones" (Sir 28:17). "Many have fallen by the edge of the sword, But not so many as have fallen by the tongue" (Sir 28:18). The tongue's bite has its own metallurgy: "For its yoke is a yoke of iron, And its bands are bands of brass" (Sir 28:20); "The death of it is an evil death, And Hades is more profitable than it" (Sir 28:21). Only the godly are sheltered: "[But] it has no power over the godly, They will not be burned in her flame" (Sir 28:22).
The tongue is also the speaker's own undoing. "Glory and shame are in the hand of one who speaks rashly; And the tongue of a man is his fall" (Sir 5:13). "A slip on the pavement is better than [a slip] of the tongue, Thus the fall of the wicked comes swiftly" (Sir 20:18). "One man slips, though not from the soul, And who has not sinned with his tongue" (Sir 19:16). Romans summarizes the diagnosis: "Their throat is an open tomb; With their tongues they have used deceit: The poison of asps is under their lips" (Ro 3:13).
Restraint, Discipline, the Watch over the Mouth
Because the tongue cuts both ways, scripture treats its discipline as a daily craft. "Whoever keeps his mouth and his tongue Keeps his soul from troubles" (Pr 21:23). "He who guards his mouth keeps his soul; [But] he who opens his lips wide will have destruction" (Pr 13:3). "He who spares his words has knowledge; And he who is of a cool spirit is a man of understanding" (Pr 17:27). "Do you see a man who is in a hurry in his words? There is more hope of a fool than of him" (Pr 29:20). "In the multitude of words transgression does not cease; But he who refrains his lips does wisely" (Pr 10:19). Ecclesiastes adds: "a time to keep silent, and a time to speak" (Ec 3:7).
The same prudence appears in Sirach as a prayer over the speaker's own mouth: "O that one would set a watch over my mouth, And a seal of shrewdness upon my lips, That I do not fall by them, And [that] my tongue does not destroy me" (Sir 22:27). "Hear, my children, [concerning] the discipline of the mouth, He who keeps [it] will not be ensnared" (Sir 23:7); "But the sinner is ensnared by his lips, And the fool stumbles through his mouth" (Sir 23:8). "See that you hedge your possession about with thorns; And for your mouth make a door and a bar" (Sir 28:24). "Bind up your silver and gold; And make a balance and weight for your words" (Sir 28:25).
Peter cites a psalm to put the same lesson plainly: "He who would love life, And see good days, Let him refrain his tongue from evil, And his lips that they speak no guile" (1Pe 3:10), echoing "Keep your tongue from evil, And your lips from speaking guile" (Ps 34:13). Even fools profit from silence: "Even a fool, when he holds his peace, is counted wise; When he shuts his lips, he is [esteemed as] prudent" (Pr 17:28); "The wise in heart will receive commandments; But a prating fool will fall" (Pr 10:8).
The Whisperer, the Talebearer, the Double Tongue
Wisdom names specific tongue-sins. The whisperer kindles fires: "If you blow upon a spark it kindles, and if you spit upon it, it is quenched; And both come forth from your mouth" (Sir 28:12). "Curse the whisperer and the double-tongued, For he has destroyed many who were at peace" (Sir 28:13). "The whisperer will turn good to evil; And he will set a conspiracy for your pleasant things" (Sir 11:31). "The whisperer defiles his own soul, And is hated wherever he sojourns" (Sir 21:28). Proverbs agrees: "A perverse man scatters abroad strife; And a whisperer separates best friends" (Pr 16:28); "For lack of wood the fire goes out; And where there is no whisperer, contention ceases" (Pr 26:20). "He who goes about as double-tongued reveals secrets; But he who is of a faithful spirit conceals a matter" (Pr 11:13). "He who goes about as a talebearer reveals secrets; Therefore don't company with him who opens his lips wide" (Pr 20:19).
Sirach warns the seasoned man not to provoke a tongue: "Do not fight with a man of tongue; And you will not put wood on a fire" (Sir 8:3); "Rash talk is feared on account of a man of tongue; And the burden on his mouth will be hated" (Sir 9:18). Boasting and slack work belong together: "Do not be boastful with your tongue, And slack and negligent with your work" (Sir 4:29). And there is speech that is itself a kind of death: "There is a manner of speech that is to be compared with death, Do not let it be found in the heritage of Jacob" (Sir 23:12); "Do not accustom your mouth to vulgar speech, For there is a sinful thing in that" (Sir 23:13); "A man who is accustomed to disgraceful talk Will not learn wisdom all his days" (Sir 23:15).
The Tongue of the Wise and the Mouth of the Righteous
The other side of the same coin: a tongue used well heals, teaches, and becomes the place where wisdom lives. "There is one who speaks rashly like the piercings of a sword; But the tongue of the wise is health" (Pr 12:18). "By long forbearing is a ruler persuaded, And a soft tongue breaks the bone" (Pr 25:15). "A word fitly spoken Is [like] apples of gold in network of silver" (Pr 25:11). "Pleasant words are [as] a honeycomb, Sweet to the soul, and health to the bones" (Pr 16:24). "The mouth of the righteous is a fountain of life" (Pr 10:11); "The mouth of the righteous talks of wisdom, And his tongue speaks justice" (Ps 37:30). The capable wife "opens her mouth with wisdom; And the law of kindness is on her tongue" (Pr 31:26).
The Servant of Isaiah is given exactly this kind of tongue: "The Sovereign Yahweh has given me the tongue of those who are taught, that I may know how to sustain with words him who is weary" (Is 50:4). Sirach echoes the praise: "Pipe and harp make sweet the song, But better than both is a pure tongue" (Sir 40:21); "A sweet mouth grows a friend; And graceful lips will greet [saying], Peace" (Sir 6:5). And a kept tongue can return praise to its giver: "Yahweh gave me the reward of my lips, And with my tongue I praise him" (Sir 51:22).
The Tongue and the Word of the Fool
Sirach holds the tongue and folly together. "A fool travails because of a word, Even as a woman travails because of a child" (Sir 19:11); "[As] an arrow stuck in the fleshy thigh, So is a word in the belly of a fool" (Sir 19:12). The wise have considered before they speak; the fool spits out everything at once: "A fool utters all his anger; But a wise man keeps it back and stills it" (Pr 29:11); "The lips of babblers [only] repeat the things that are not theirs, But the words of the wise are weighed in the balance" (Sir 21:25); "The heart of fools is in their mouth, But the mouth of the wise is [in] their heart" (Sir 21:26).
The Tongue Confessing — and the Tongue Denying
Speech turns into self-positioning before God. The duty of confession runs across the canon. "if you will confess with your mouth the Lord Jesus, and will believe in your heart that God raised him from the dead, you will be saved" (Ro 10:9). "Whoever will confess that Jesus is the Son of God, God stays in him, and he in God" (1Jn 4:15). "Everyone who will confess me before men, the Son of Man will also confess him before the angels of God" (Lu 12:8). The eschatological horizon of confession is universal: "and that every tongue should confess, The Lord Jesus Christ, to the glory of God the Father" (Php 2:11). The Babel scattering ends, in this idiom, in a single confession from all tongues.
The opposite verbal act is denial. "Whoever denies the Son, the same doesn't have the Father" (1Jn 2:23). "if we will deny him, he also will deny us" (2Ti 2:12). "For whoever will be ashamed of me and of my words in this adulterous and sinful generation, the Son of Man will also be ashamed of him, when he comes in the glory of his Father with the holy angels" (Mr 8:38).
The Gift of Tongues in the Assembly
Among the gifts distributed in the Corinthian church Paul lists "[diverse] kinds of tongues" alongside "the interpretation of tongues" (1Co 12:10). His extended treatment in the next chapters frames the gift, ranks it, and orders its use.
Tongues belong on the temporary side of the gifts ledger: "Love never fails: but if [there are] prophecies, they will be done away; if [there are] tongues, they will cease; if [there is] knowledge, it will be done away" (1Co 13:8).
In 1 Corinthians 14 Paul lays out the gift's character. "For he who speaks in a tongue speaks not to men, but to God; for no man understands; but in the spirit he speaks mysteries" (1Co 14:2). "He who speaks in a tongue edifies himself; but he who prophesies edifies the church" (1Co 14:4). "Now I would have all of you⁺ speak with tongues, yet even better that you⁺ should prophesy: and greater is he who prophesies than he who speaks with tongues, except he interprets, that the church may receive edifying" (1Co 14:5). The argument turns on intelligibility: "unless you⁺ utter by the tongue speech easy to understand, how will it be known what is spoken? For you⁺ will be speaking into the air" (1Co 14:9). The speaker should pray for the matching gift of interpretation: "Therefore let him who speaks in a tongue pray that he may interpret" (1Co 14:13). "For if I pray in a tongue, my spirit prays, but my understanding is unfruitful" (1Co 14:14). Paul's own ranking: "I thank God, I speak with tongues more than all of you⁺: nevertheless in the church I would rather speak five words with my understanding, that I might instruct others also, than ten thousand words in a tongue" (1Co 14:18-19).
The gift's sign-function is drawn from Isaiah: "In the law it is written, By men of strange tongues and by the lips of strangers I will speak to this people; and not even thus will they hear me, says the Lord" (1Co 14:21). "Therefore tongues are for a sign, not to those who believe, but to the unbelieving" (1Co 14:22). Used unintelligibly in assembly, however, tongues misfire as a sign: "If therefore the whole church is assembled together and all speak with tongues, and unlearned or unbelieving men come in, will they not say that you⁺ are insane?" (1Co 14:23).
The order-of-worship rules are direct. "If any man speaks in a tongue, [let it be] by two, or at the most three, and [that] in turn; and let one interpret: but if there is no interpreter, let him keep silent in the church; and let him speak to himself, and to God" (1Co 14:27-28). And the closing pastoral admonition: "Therefore, my brothers, desire earnestly to prophesy, and do not forbid to speak with tongues" (1Co 14:39).
The gift is cataloged with the rest: "And God has set some in the church, first apostles, second prophets, third teachers, then miracles, then gifts of healings, helps, governments, [diverse] kinds of tongues" (1Co 12:28); "Do all speak with tongues? Do all interpret?" (1Co 12:30).
A Note on Pentecost
The TONGUE and TONGUES heading sends the reader to the Acts narratives at Pentecost (Ac 2), in Cornelius's house (Ac 10:46), and at Ephesus (Ac 19:6). The UPDV does not carry the book of Acts, so those references cannot be quoted here. The shape of Paul's argument in 1 Corinthians 12 and 14 — the gift, its ranking, its limits — stands as the umbrella's New Testament evidence on tongues.
