Proverbs 20:19-22

He who goes about as a gossip reveals secrets; Therefore do not associate with a gossip [who talks freely or flatters]. [Rom 16:17, 18] Whoever curses his father or his mother, His lamp [of life] will be extinguished in time of darkness. An inheritance hastily gained [by greedy, unjust means] at the beginning Will not be blessed in the end. [Prov 28:20; Hab 2:6] Do not say, “I will repay evil”; Wait [expectantly] for the LORD, and He will rescue and save you. [Deut 32:35; 2 Sam 16:12; Rom 12:17-19; 1 Thess 5:15; 1 Pet 3:9]
