Saul’s son had two men who were commanders of raiding 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 is also reckoned to Benjamin, Bible see other translations

“commanders of raiding bands.” It is possible that these two men got to be leaders because they were from the tribe of Benjamin, the tribe of Saul, and Ish-bosheth. Because they were from Benjamin they should have been expected to have been especially loyal to the house of Saul, but obviously, they were not.

These men were part of the people of Benjamin who moved into Beeroth, which was originally a Gibeonite city (Josh. 9:17), but most of the Gibeonites moved out as 2 Samuel 4:3 says.

“Beeroth.” Originally a Hivite city, it became part of the tribal allotment of Benjamin.
