2 Samuel 4:1-4

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.
