2 Samuel 4:7-8

7Now when they had come into the house, as he was lying on his bed in his bedroom, they struck him and killed him, and they beheaded him. And they took his head and 12traveled by way of the Arabah all night. 8Then they brought the head of Ish-bosheth to David at Hebron, and said to the king, “Behold, the head of Ish-bosheth 3the son of Saul, your enemy, who sought your life; so the Lord has given my lord the king vengeance this day on Saul and his 4descendants.”
