Almost any verse in Proverbs can be usefully quoted. I don’t make out that these are of any special significance. But they do present some common theme.
A couple of my favorites.
Proverbs 17:28 Even a fool, when he holdeth his peace, is counted wise: and he that shutteth his lips is esteemed a man of understanding.
Proverbs 20:12 The hearing ear, and the seeing eye, the LORD hath made even both of them.
Here is a theme of work and effort, and the consequence.
Pro 20:4 The sluggard will not plow by reason of the cold; therefore shall he beg in harvest, and have nothing.
Pro 19:15 Slothfulness casteth into a deep sleep; and an idle soul shall suffer hunger.
Pro 14:4 Where no oxen are, the crib is clean: but much increase is by the strength of the ox.
Also observe the importance of just accountings.
Pro 16:11 A just weight and balance are the LORD’S: all the weights of the bag are his work.
Pro 20:10 Divers weights, and divers measures, both of them are alike abomination to the LORD.
Pro 20:23 Divers weights are an abomination unto the LORD; and a false balance is not good.
Curiously this is repeated twice in Chapter 20.
Proverbs 20:10 Gill
Divers weights, and divers measures,…. Or, “a stone and a stone, and an ephah and an ephah” (d). Stones being in old time used in weighing, and an “ephah” was a common measure among the Jews; and these ought not to be different; one stone or weight for buying, and another for selling; and one measure to buy goods in with, and another to sell out with; the one too heavy, the other too light; the one too large, and the other too scanty; whereby justice is not done between man and man; whereas they ought to be just and equal, Lev 19:35;
both of them are alike abomination to the Lord; who loves righteousness and hates iniquity, and requires of men to do justly; and abhors every act of injustice, and whatever is detrimental to men’s properties; see Pro 11:1.
(d) So Montanus, Schulteus.
Proverbs 20:23 Gill
Divers weights are an abomination unto the Lord,…. See Gill on Pro 20:10; which is here repeated for the further confirmation of it, and that it might be taken notice of and avoided; and perhaps this sin of using false weights and measures was common with the Jews;
and a false balance is not good; in the sight of God; but an abomination, as in Pro 11:1; nor is it good for men in the issue; for though they may gain by it at present, it will prove a loss to them in the end, since it will bring a curse on all they get.
