2 Samuel 4
7 Ref And when they came into the house, Ish-bosheth was stretched on his bed in his bedroom; and they made an attack on him and put him to death, and, cutting off his head, they took it with them and went by the road through the Arabah all night.
8 Ref And they took the head of Ish-bosheth to David in Hebron, and said to the king, Here is the head of Ish-bosheth, the son of Saul your hater, who would have taken your life; the Lord has taken payment for the wrongs of my lord the king from Saul and his seed today.
