Matthew Henry commentary on Proverbs 12:17-22
Embedded KJV/source Scripture
19 The lip of truth shall be established for ever: but a lying tongue is but for a moment.
Be it observed, to the honour of truth, that sacred thing, 1. That, if truth be spoken, it will hold good, and, whoever may be disobliged by it and angry at it, yet it will keep its ground. Great is the truth and will prevail. What is true will be always true; we may abide by it, and need not fear being disproved and put to shame. 2. That, if truth be denied, yet in time it will transpire. A lying tongue, that puts false colours upon things, is but for a moment. The lie will be disproved. The liar, when he comes to be examined, will be found in several stories, and not consistent with himself as he is that speaks truth; and, when he is found in a lie, he cannot gain his point, nor will he afterwards be credited. Truth may be eclipsed, but it will come to light. Those therefore that make a lie their refuge will find it a refuge of lies.
Weighty Sayings.

20 Deceit is in the heart of them that imagine evil: but to the counsellors of peace is joy.
Note, 1. Those that devise mischief contrive, for the accomplishing of it, how to impose upon others; but it will prove, in the end, that they deceive themselves. Those that imagine evil, under colour of friendship, have their hearts full of this and the other advantage and satisfaction which they shall gain by it, but it is all a cheat. Let them imagine it ever so artfully, deceivers will be deceived. 2. Those that consult the good of their neighbours, that study the things which make for peace and give peaceable advice, promote healing attempts and contrive healing methods, and, according as their sphere is, further the public welfare, will have not only the credit, but the comfort of it. They will have joy and success, perhaps beyond their expectation. Blessed are the peace-makers.

21 There shall no evil happen to the just: but the wicked shall be filled with mischief.
Note, 1. Piety is a sure protection. If men be sincerely righteous, the righteous God has engaged that no evil shall happen to them. He will, by the power of his grace in them, that principle of justice, keep them from the evil of sin; so that, though they be tempted, yet they shall not be overcome by the temptation, and though they may come into trouble, into many troubles, yet to them those troubles shall have no evil in them, whatever they have to others ( Ps. xci. 10 ), for they shall be overruled to work for their good. 2. Wickedness is as sure a destruction. Those that live in contempt of God and man, that are set on mischief, with mischief they shall be filled. They shall be more mischievous, shall be filled with all unrighteousness, Rom. i. 29 . Or they shall be made miserable with the mischiefs that shall come upon them. Those that delight in mischief shall have enough of it. Some read the whole verse thus, There shall no evil happen to the just, though the wicked be filled with mischief and spite against them. They shall be safe under the protection of Heaven, though hell itself break loose upon them.

22 Lying lips are abomination to the Lord : but they that deal truly are his delight.
We are here taught, 1. To hate lying, and to keep at the utmost distance from it, because it is an abomination to the Lord, and renders those abominable in his sight that allow themselves in it, not only because it is a breach of his law, but because it is destructive to human society. 2. To make conscience of truth, not only in our words, but in all our actions, because those that deal truly and sincerely in all their dealings are his delight, and he is well pleased with them. We delight to converse with, and make use of, those that are honest and that we may put a confidence in; such therefore let us be, that we may recommend ourselves to the favour both of God and man.

23 A prudent man concealeth knowledge: but the heart of fools proclaimeth foolishness.
Note, 1. He that is wise does not affect to proclaim his wisdom, and it is his honour that he does not. He communicates his knowledge when it may turn to the edification of others, but he conceals it when the showing of it would only tend to his own commendation. Knowing men, if they be prudent men, will carefully avoid every thing that savours of ostentation, and not take all occasions to show their learning and reading, but only to use it for good purposes, and then let their own works praise them. Ars est celare artem—The perfection of art is to conceal it. 2. He that is foolish cannot avoid proclaiming his folly, and it is his shame that he cannot: The heart of fools, by their foolish words and actions, proclaims foolishness; either they do not desire to hide it, so little sense have they of good and evil, honour and dishonour, or they know not how to hide it, so little discretion have they in the management of themselves, Eccl. x. 3 .

24 The hand of the diligent shall bear rule: but the slothful shall be under tribute.
Note, 1. Industry is the way to preferment. Solomon advanced Jeroboam because he saw that he was an industrious young man, and minded his business, 1 Kings xi. 28 . Men that take pains in study and serviceableness will thereby gain such an interest and reputation as will give them a dominion over all about them, by which means many have risen strangely. He that has been faithful in a few things shall be made ruler over many things. The elders, that labour in the word and doctrine, are worthy of double honour; and those that are diligent when they are young will get that which will enable them to rule, and so to rest, when they are old. 2. Knavery is the way to slavery: The slothful and careless, or rather the deceitful (for so the word signifies), shall be under tribute. Those that, because they will not take pains in an honest calling, live by their shifts and arts of dishonesty, are paltry and beggarly, and will be kept under. Those that are diligent and honest when they are apprentices will come to be masters; but those that are otherwise are the fools who, all their days, must be servants to the wise in heart.
