Proverbs 14:29 He that is slow to wrath is of great understanding: but he that is hasty of spirit exalts folly. 

‘He that is slow to wrath is of great understanding: but he that is hasty of spirit exalted folly.’ A wise man is slow to wrath, but a fool is hasty of spirit and magnifies folly.

‘But he that is hasty of spirit.’ Four examples of a hasty spirit: Rehoboam (1Kin. 12:1-33). Jehoram (2Kin. 5:7). Jonah (Jon. 4:8-9). Martha (Luke 10:40).

Man is advised to be “slow to wrath” (Jas. 1:19). Anyone slow to anger is “of great understanding” (14:29), “appeaseth strife” (15:18), and “is better than the mighty” (16:32).

There are seven commands to Christians: Be swift to hear (Jas. 1:19). Be slow to speak. Be slow to wrath. Lay aside all filthiness (Jas. 1:21). Lay aside all overflowing of wickedness. Receive the Word with meekness. Be doers of the Word (Jas. 1:22).
