2 Samuel 4:1-3

And when Ish-bosheth, Saul’s son, heard that Abner was dead in Hebron, his hands became feeble, and all the Israelites were troubled. And Ish-bosheth, 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 the Beerothite, of the children of Benjamin (for Beeroth also is reckoned to Benjamin: and the Beerothites fled to Gittaim, and have been sojourners there until this day).
