II Samuel 4:1-3

When Saul’s son heard that Abner had died in Hebron, he lost heart, and all Israel was troubled. Now Saul’s son had two men who were captains of troops. The name of one was Baanah and the name of the other Rechab, the sons of Rimmon the Beerothite, of the children of Benjamin. (For Beeroth also was part of Benjamin, because the Beerothites fled to Gittaim and have been sojourners there until this day.)
