2 Samuel 4:1-5

Now when Ish-bosheth, Saul’s son, heard that Abner had died in Hebron, he lost courage, and all Israel was disturbed. Saul’s son had two men who were commanders of bands: 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 been aliens there until this day). Now Jonathan, Saul’s son, had a son crippled in his feet. He was five years old when the report of Saul and Jonathan came from Jezreel, and his nurse took him up and fled. And it happened that in her hurry to flee, he fell and became lame. 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.
