Proverbs 22:24-25; Proverbs 17:14; Proverbs 17:19; Proverbs 26:21

24 Do not make friends with a hot-tempered person, do not associate with one easily angered, 25 or you may learn their ways and get yourself ensnared.
14 Starting a quarrel is like breaching a dam; so drop the matter before a dispute breaks out.
19 Whoever loves a quarrel loves sin; whoever builds a high gate invites destruction.
21 As charcoal to embers and as wood to fire, so is a quarrelsome person for kindling strife.
