2 Samuel 4:2-6

And Saul’s son had two men who were commanders of troops: the name of the one was Baanah, and the name of the other Rechab, sons of Rimmon the Beerothite, of the sons of Benjamin (for Beeroth is also considered part of Benjamin,

and the Beerothites fled to Gittaim and have lived there as strangers until this day).

Now Jonathan, Saul’s son, had a son who was disabled in both feet. He was five years old when the news of Saul and Jonathan came from Jezreel, and his nurse picked him up and fled. But it happened that in her hurry to flee, he fell and could no longer walk. And his name was Mephibosheth.

So the sons of Rimmon the Beerothite, Rechab and Baanah, departed and came to the house of Ish-bosheth in the heat of the day, while he was taking his midday rest.

And they came to the interior of the house as if to get wheat, and they struck him in the belly; and Rechab and his brother Baanah escaped.
