Jibhar was one of King David's sons, born in Jerusalem after David had conquered the city and made it his capital. He is mentioned in the genealogies of David's sons but plays no prominent role in the biblical narratives beyond this. His name means 'he chooses' or 'the chosen one'.
David's conquest of Jerusalem and establishing the city as his capital was the context for Jibhar's birth, as David took more wives and had more sons and daughters there.
6The king and his men marched on Jerusalem against the Jebusites who lived there. They said to David, "You will never get in here. Even the blind and the lame could drive you off"—meaning, "David will never get in here."
