2 Samuel 16:8; 2 Samuel 16:9

8 The LORD has repaid you for all the blood you shed in the household of Saul, in whose place you have reigned. The LORD has given the kingdom into the hands of your son Absalom. You have come to ruin because you are a murderer!”

9 Then Abishai son of Zeruiah said to the king, “Why should this dead dog curse my lord the king? Let me go over and cut off his head.”
