2nd Samuel 4:3

1 And when Saul's son Ish-bosheth had news that Abner was dead in Hebron, his hands became feeble, and all the Israelites were troubled.

2 And Saul's son had two men, captains of bands, one named Baanah and the other Rechab, sons of Rimmon the Beerothite, of the tribe of Benjamin; (for Beeroth was at one time taken to be part of Benjamin:

3 But the people of Beeroth had gone in flight to Gittaim, where they have been living to this day.)

4 Now Jonathan, Saul's son, had a son whose feet were damaged. He was five years old when news of the death of Saul and Jonathan came from Jezreel, and the woman who took care of him took him up and went in flight: and while she was getting him away as quickly as she was able, he had a fall and his feet were damaged. His name was Mephibosheth.

5 And Rechab and Baanah, the sons of Rimmon the Beerothite, went out and came to the house of Ish-bosheth in the heat of the day, when he was resting in the middle of the day. Now the woman who kept the door was cleaning grain, and sleep overcame her.

6 And Rechab and his brother Baanah got in without being seen.

7 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.
