II Samuel 4:1-5

When Saul’s son heard that Abner had died in Hebron, he lost heart, and all Israel was troubled. Now Saul’s son had two men who were captains of troops. The name of one was Baanah and the name of the other Rechab, the sons of Rimmon the Beerothite, of the children of Benjamin. (For Beeroth also was part of Benjamin, because the Beerothites fled to Gittaim and have been sojourners there until this day.) Jonathan, Saul’s son, had a son who was lame in his feet. He was five years old when the news about Saul and Jonathan came from Jezreel; and his nurse took him up and fled. And it happened, as she made haste to flee, that he fell and became lame. His name was Mephibosheth. Then the sons of Rimmon the Beerothite, Rechab and Baanah, set out and came at about the heat of the day to the house of Ishbosheth, who was lying on his bed at noon.
