But I say unto you ... - Christ closes this address to his malignant and wicked hearers by a solemn declaration that for these things God would bring them into judgment. Therefore. They who had spoken so malignantly against him, could not escape.

Idle word - This literally means a vain, thoughtless, useless word; a word that accomplishes no good. Here it means, evidently, "wicked, injurious, false, malicious, for such" were the words which they had spoken.

Every idle word - Ρημα αργον, a word that does nothing, that neither ministers grace nor instruction to them who hear it. The word αργον corresponds to the Hebrew שוא shave, which signifies not only vain or empty, but also wicked and injurious, such as a false testimony against a neighbor, compare Deuteronomy 5:11, Deuteronomy 5:20. Add to this, that Symmachus translates פגול piggul, polluted, Leviticus 19:7, by the very Greek word in the text. It was to explain this ambiguous meaning of the word, that ten MSS. have changed αργον into πονηρον, evil. Our Lord must be understood here as condemning all false and injurious words: the scope of the place necessarily requires this meaning.

But I say unto you,.... This form of speaking is used, the more strongly to asseverate the truth of what is after said; and the rather, because men are apt to indulge a liberty with their tongues; fancying no great crime is committed, when only words are spoken, and no facts done;

that every idle word that a man shall speak, they shall give account thereof in the day of judgment. By an "idle word" is meant, what the Jews call, , "light conversation", and , "vain discourse", as the Hebrew Gospel of Munster reads it here; frothy language, unprofitable talk, which, though it does not directly hurt God or man, yet is of no use to speaker or hearer; and yet even this, in the last general and awful judgment, if not forgiven, and repented of, must be accounted for; and much more such horrid blasphemies the Pharisees had vented against Christ, and the Spirit of Christ. The Jews (d) have a saying pretty much like this,

"That even , "for any light conversation", which passes between a man and his wife, he shall "be brought to judgment".''

(d) R. Jonah apud L. Capell. in loc.

Idle (ἀργὸν)

A good rendering. The word is compounded of ἀ, not, and ἔργον, work. An idle word is a non-working word; an inoperative word. It has no legitimate work, no office, no business, but is morally useless and unprofitable.

But I say unto you, That every {e} idle word that men shall speak, they shall give account thereof in the day of judgment.

(e) Vain and unprofitable trifles, which for the most part, men spend their lives in search of.

12:36 Every idle word. If we shall be called on to give account for every idle, rash, inconsiderate word, how much more for such blasphemy as the Pharisees had uttered? How careful, too, should we be to see that our speech is pure!

12:36 Ye may perhaps think, God does not so much regard your words. But I say to you - That not for blasphemous and profane words only, but for every idle word which men shall speak - For want of seriousness or caution; for every discourse which is not conducive to the glory of God, they shall give account in the day of judgment.

36. But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment-They might say, "It was nothing: we meant no evil; we merely threw out a supposition, as one way of accounting for the miracle we witnessed; if it will not stand, let it go; why make so much of it, and bear down with such severity for it?" Jesus replies, "It was not nothing, and at the great day will not be treated as nothing: Words, as the index of the heart, however idle they may seem, will be taken account of, whether good or bad, in estimating character in the day of judgment."

12:33-37 Men's language discovers what country they are of, likewise what manner of spirit they are of. The heart is the fountain, words are the streams. A troubled fountain, and a corrupt spring, must send forth muddy and unpleasant streams. Nothing but the salt of grace, cast into the spring, will heal the waters, season the speech, and purify the corrupt communication. An evil man has an evil treasure in his heart, and out of it brings forth evil things. Lusts and corruptions, dwelling and reigning in the heart, are an evil treasure, out of which the sinner brings forth bad words and actions, to dishonour God, and hurt others. Let us keep constant watch over ourselves, that we may speak words agreeable to the Christian character.
