Proverbs 20:16; Proverbs 20:22; Proverbs 20:3

16 Be sure to get collateral from anyone who guarantees the debt of a stranger. Get a deposit if someone guarantees the debt of a foreigner.
22 Don't say, "I will get even for this wrong." Wait for the LORD to handle the matter.
3 Avoiding a fight is a mark of honor; only fools insist on quarreling.
