2 Samuel 4:5-8

4:5 Now the sons of Rimmon the Beerothite – Recab and Baanah – went at the hottest part of the day to the home of Ish-bosheth, as he was enjoying his midday rest. 4:6 They entered the house under the pretense of getting wheat and mortally wounded him in the stomach. Then Recab and his brother Baanah escaped.

4:7 They had entered the house while Ish-bosheth was resting on his bed in his bedroom. They mortally wounded him and then cut off his head. Taking his head, they traveled on the way of the Arabah all that night. 4:8 They brought the head of Ish-bosheth to David in Hebron, saying to the king, “Look! The head of Ish-bosheth son of Saul, your enemy who sought your life! The Lord has granted vengeance to my lord the king this day against Saul and his descendants!”
