2 Samuel 4:7-8

7(They had come into the house while Ishbosheth was sleeping on his bed in his bedroom. They stabbed him, killed him, and cut off his head.) They took his head and traveled all night along the road to the plains.

8They brought Ishbosheth’s head to David at Hebron. “Here is the head of Ishbosheth, the son of your enemy Saul who tried to kill you,” they told the king. “Today the Lord has given Your Royal Majesty revenge on Saul and his descendants.”
