2 Samuel 4:1-3

When Ish-Bosheth son of Saul heard that Abner had died in Hebron, he lost courage, and all Israel became alarmed. Now Saul’s son had two men who were leaders of raiding bands. One was named Baanah and the other Rekab; they were sons of Rimmon the Beerothite from the tribe of Benjamin—Beeroth is considered part of Benjamin, because the people of Beeroth fled to Gittaim and have resided there as foreigners to this day.
