2 Samuel 4:2-4

Now the son of Saul had two men who were leaders of raiding bands. The name of one was Baanah and the name of the other Rekab, both sons of Rimmon the Beerothite, from among the sons of Benjamin. Now Beeroth is also regarded as part of Benjamin, because the Beerothites fled to Gittaim and have been sojourners there until this day. Now Jonathan the son of Saul had a son with crippled feet. He was five years old when the report of Saul and Jonathan came from Jezreel. His nurse picked him up and fled, but in her haste to escape, he fell and became lame. His name was Mephibosheth.
