Proverbs 24:8; Proverbs 24:17-18; Proverbs 24:29

8 Whoever plots evil will be known as a schemer.
17 Do not gloat when your enemy falls; when they stumble, do not let your heart rejoice, 18 or the LORD will see and disapprove and turn his wrath away from them.
29 Do not say, “I’ll do to them as they have done to me; I’ll pay them back for what they did.”
