2nd Samuel 16:8

5 And when King David came to Bahurim, a man of Saul's family named Shimei, the son of Gera, came out from there, calling curses after him.

6 And he sent stones at David and at all the king's servants and at all the people and at all the men of war by his side, on the right hand and on the left.

7 And Shimei said, with curses, Be gone, be gone, you man of blood, you good-for-nothing:

8 The Lord has sent punishment on you for all the blood of the family of Saul, whose kingdom you have taken; and the Lord has given the kingdom to Absalom, your son: now you yourself are taken in your evil, because you are a man of blood.

9 Then Abishai, the son of Zeruiah, said to the king, Is this dead dog to go on cursing my lord the king? let me go over and take off his head.

10 And the king said, What have I to do with you, you sons of Zeruiah? Let him go on cursing, for the Lord has said, Put a curse on David, and who then may say, Why have you done so?

11 And David said to Abishai and to all his servants, You see how my son, the offspring of my body, has made designs against my life: how much more then may this Benjamite do so? Let him be, and let him go on cursing; for the Lord has given him orders.
