Proverbs 14:17

[He that is] soon angry dealeth foolishly
A man that is quick and short, of a hasty spirit, and presently discovers anger and resentment in his face; he says and does many foolish things, which he afterwards is sorry for, and repents, and is ashamed of; and he is to be pitied and forgiven; and a man of wicked devices is hated;
one that hides his anger, covers his resentment, contrives schemes to revenge himself, and waits an opportunity to put them in execution, is justly hateful to God and men.
