2 Samuel 4:2-3

4:2 Now Saul’s son had two men who were in charge of raiding units; one was named Baanah and the other Recab. They were sons of Rimmon the Beerothite, who was a Benjaminite. (Beeroth is regarded as belonging to Benjamin, 4:3 for the Beerothites fled to Gittaim and have remained there as resident foreigners until the present time.)
