2 Samuel 4:1-3

Now when Ish-bosheth, Saul’s son, heard that Abner had died in Hebron, he lost courage, and all Israel was disturbed. Saul’s son had two men who were commanders of bands: the name of the one was Baanah and the name of the other Rechab, sons of Rimmon the Beerothite, of the sons of Benjamin (for Beeroth is also considered part of Benjamin, and the Beerothites fled to Gittaim and have been aliens there until this day).
