Elisha's story is related in the Books of Kings (Second Scroll, chapters 2–14) in the Hebrew Bible (part of the Nevi'im). According to this story, he was a prophet and a wonder-worker of the Kingdom of Israel who was active during the reigns of Joram, Jehu, Jehoahaz, and Jehoash (Joash). Elisha was the son of Shaphat, a wealthy land-owner of Abel-meholah; he became the attendant and disciple of Elijah.
His name first occurs in chapter 19 of the Books of Kings in the command given to Elijah to anoint him as his successor. After learning in the cave on Mount Horeb, that Elisha, the son of Shaphat, had been selected by Yahweh as his successor in the prophetic office, Elijah set out to find him.
