Proverbs 22:24–25

"Don't befriend angry people   or associate with hot-tempered people, or you will learn to be like them   and endanger your soul." These verses give us permission to avoid close relationships with angry or "toxic" people. You may not be able to avoid them altogether, but you can avoid getting too close. You can avoid constant association with them. You can be pleasant and kind, but keep your distance. These verses imply that angry people are actually dangerous to your soul. They will bring you down to their level, every time. You become like those you associate with regularly.
