Verse 17. - He that speaketh - breatheth out fearlessly (Proverbs 6:19) - truth showeth forth righteousness. The truth always conduces to justice and right, not only in a matter of law, but generally and in all cases. Vulgate, "He who speaks that which he knows is a discoverer of justice;" Septuagint, "A just man announces well proved assurance [or, 'the open truth'] (ἐπιδεικνυμένην πίστιν)." A false witness showeth forth deceit (Proverbs 14:5, 25); exhibits his true character, which is fraud, treachery, and wrong doing.

12:16. A foolish man is soon angry, and is hasty in expressing it; he is ever in trouble and running into mischief. It is kindness to ourselves to make light of injuries and affronts, instead of making the worst of them. 17. It is good for all to dread and detest the sin of lying, and to be governed by honesty. 18. Whisperings and evil surmises, like a sword, separate those that have been dear to each other. The tongue of the wise is health, making all whole. 19. If truth be spoken, it will hold good; whoever may be disobliged, still it will keep its ground. 20. Deceit and falsehood bring terrors and perplexities. But those who consult the peace and happiness of others have joy in their own minds. 21. If men are sincerely righteous, the righteous God has engaged that no evil shall happen to them. But they that delight in mischief shall have enough of it. 22. Make conscience of truth, not only in words, but in actions. 23. Foolish men proclaim to all the folly and emptiness of their minds. 24. Those who will not take pains in an honest calling, living by tricks and dishonesty, are paltry and beggarly. 25. Care, fear, and sorrow, upon the spirits, deprive men of vigour in what is to be done, or courage in what is to be borne. A good word from God, applied by faith, makes the heart glad. 26. The righteous is abundant; though not in this world's goods, yet in the graces and comforts of the Spirit, which are the true riches. Evil men vainly flatter themselves that their ways are not wrong. 27. The slothful man makes no good use of the advantages Providence puts in his way, and has no comfort in them. The substance of a diligent man, though not great, does good to him and his family. He sees that God gives it to him in answer to prayer. 28. The way of religion is a straight, plain way; it is the way of righteousness. There is not only life at the end, but life in the way; all true comfort.He that speaketh truth showeth forth righteousness,.... He that "blows" or "breathes out truth" (d), as the word signifies; that utters it freely and fully without any hesitation; that speaks nothing but truth, and speaks out the whole truth without any reserve; such a man upon every occasion will declare that which is just and right, and show himself to be an honest and upright man; he that uses himself to speak truth in common conversation, will, in a court of judicature, whether upon his oath or not, testify that which is just and the real matter of fact; there is a connection between truth and righteousness, for though they are distinct things they go together, what is true is just, and what is just is true; so he that speaks the truth of the Gospel, or is a faithful preacher of it, will show forth righteousness, what is the righteousness of the law, and what is the righteousness of faith; how insufficient a man's own righteousness is to justify him in the sight of God; the necessity of the righteousness of Christ, how free and full, excellent and glorious, suitable and useful it is, Romans 1:17;

but a false witness deceit; that is, one that is used to lying, when he is called to give testimony upon any affair in judgment, he will declare that which is false and deceitful, having no regard to truth and justice. So a false teacher, instead of showing men the insufficiency of their own righteousness, and directing them to the righteousness of Christ for justification, will utter deceitful doctrine, and build up their hopes upon the sandy and deceitful foundation of their own works; as Popish teachers, and such as verge towards them.
