2 Samuel 4:1-3

And when Saul's son heard that Abner was dead in Hebron, his hands were feeble, and all the Israelites were troubled. And Saul's son had two men that were captains of bands: the name of the one was Baanah, and the name of the other Rechab, the sons of Rimmon a Beerothite, of the children of Benjamin: (for Beeroth also was reckoned to Benjamin: and the Beerothites fled to Gittaim, and were sojourners there until this day.)
