2 Samuel 4:1-5

When Saul’s son Ish-bosheth [king of Israel], heard that Abner had died in Hebron, he lost courage, and all Israel was horrified. Saul’s son had two men who were commanders of [raiding] bands [of soldiers]. One was named Baanah and the other Rechab, the sons of Rimmon the Beerothite of the sons (tribe) of Benjamin (for Beeroth is also considered part of [the tribe of] Benjamin, and the Beerothites fled to Gittaim, and have been resident aliens there to this day). Jonathan, Saul’s son, had a son whose feet were crippled. He was five years old when the news [of the deaths] of Saul and Jonathan came from Jezreel. And the boy’s nurse picked him up and fled; but it happened that while she was hurrying to flee, he fell and became lame. His name was Mephibosheth. So the sons of Rimmon the Beerothite, Rechab and Baanah, left and came to the house of Ish-bosheth in the heat of the day while he was taking his midday rest.
