2 Samuel 16:5-8, 9-10

When the king got to Bahurim, a man appeared who had connections with Saul’s family. His name was Shimei son of Gera. As he followed along he shouted insults and threw rocks right and left at David and his company, servants and soldiers alike. To the accompaniment of curses he shouted, “Get lost, get lost, you butcher, you hellhound! GOD has paid you back for all your dirty work in the family of Saul and for stealing his kingdom. GOD has given the kingdom to your son Absalom. Look at you now—ruined! And good riddance, you pathetic old man!”

Abishai son of Zeruiah said, “This mangy dog can’t insult my master the king this way—let me go over and cut off his head!” But the king said, “Why are you sons of Zeruiah always interfering and getting in the way? If he’s cursing, it’s because GOD told him, ‘Curse David.’ So who dares raise questions?”
