Proverbs 22.24-25

24 “Make no friendship with an angry man; and with a furious man thou shalt not go:

25 Lest thou learn his ways, and get a snare to thy soul.”

Ecclesiastes 7

9 Be not hasty in thy spirit to be angry: for anger resteth in the bosom of fools.

10 Say not thou, What is the cause that the former days were better than these? for thou dost not inquire wisely concerning this.

20 For there is not a just man upon earth, that doeth good, and sinneth not.

21 Also take no heed unto all words that are spoken; lest thou hear thy servant curse thee:

22 For oftentimes also thine own heart knoweth that thou thyself likewise hast cursed others.
