(5) Thy mouth uttereth thine iniquity.--These words may mean either "Thy mouth teacheth thine iniquity," or "Thine iniquity teacheth thy mouth," and the second clause must be taken adversatively or otherwise according as we understand the meaning, "Thy mouth proclaimeth thine iniquity, though thou choosest the tongue of the crafty, and so contrivest in some degree to conceal it;" or, "Thine iniquity teacheth thy mouth its eloquence, and by consequence thou choosest the tongue of the crafty." We incline to the latter, though it is fair to say that the next verse seems rather to favour the other meaning.

Verse 5. - For thy mouth uttereth thine iniquity. Some render, "Thine iniquity teacheth thy mouth," causing it to utter such profane speeches (Vulgate, Dillmann, Canon Cook, Revised Version); but the translation of the Authorized Version is defensible on grammatical grounds, and yields a good sense, so that no alteration is necessary. And thou choosest the tongue of the crafty; or, the tongue of the subtle (comp. Genesis 3:1, where the epithet assigned to the serpent is the same). Eliphaz probably means to tax Job with cloaking his real impiety under a pretence of religiousness.

15:1-16 Eliphaz begins a second attack upon Job, instead of being softened by his complaints. He unjustly charges Job with casting off the fear of God, and all regard to him, and restraining prayer. See in what religion is summed up, fearing God, and praying to him; the former the most needful principle, the latter the most needful practice. Eliphaz charges Job with self-conceit. He charges him with contempt of the counsels and comforts given him by his friends. We are apt to think that which we ourselves say is important, when others, with reason, think little of it. He charges him with opposition to God. Eliphaz ought not to have put harsh constructions upon the words of one well known for piety, and now in temptation. It is plain that these disputants were deeply convinced of the doctrine of original sin, and the total depravity of human nature. Shall we not admire the patience of God in bearing with us? and still more his love to us in the redemption of Christ Jesus his beloved Son?For thy mouth uttereth thine iniquity,.... Which was in his heart, and so was an evidence against him, and proved him perverse, and made good the above charges exhibited against him: or "thine iniquity teaches thy mouth" (y); the wickedness that was in his heart prompted his mouth to speak the things he did, see Matthew 12:34; and this, as it was an instance of his folly, Proverbs 15:2; so a proof of his casting off the fear of the Lord; for if that had been before his eyes, he would have bridled his lips, and not uttered all the wickedness of his heart: for he that "bridleth not his tongue, this man's religion is vain", James 1:26;

and thou choosest the tongue of the crafty; coloured over things under specious pretences of religion and godliness, so that the simple and ignorant took him for a holy good man, when he was at heart an hypocrite; in this light Eliphaz puts Job, as one that walked and talked in craftiness, and was a deceitful worker, and imposed upon men with false glosses and plausible pretences.
