2 Samuel 16:9-11

9Then Zeruiah's son, Abishai, said to the king, ‘This man is only a useless dog! He must not curse you, my lord the king. I should go and cut off his head!’

10The king said, ‘No! You sons of Zeruiah should not tell me what to do! Perhaps he is cursing me because the Lord has said to him, “Curse David.” Then we cannot say that he is wrong to curse me.’

11Then David said to Abishai and to all his officers, ‘My own son is trying to kill me. Now this man from Benjamin's tribe wants to do the same thing. The Lord has told him to do this, so do not stop him cursing me.
