Who succeeded Elijah as prophet?

Answer: Elisha

God told Elijah to anoint Elisha to succeed him as prophet; later the prophets said, "The spirit of Elijah rests on Elisha."

“You are also to anoint Jehu son of Nimshi as king over Israel and Elisha son of Shaphat from Abel-meholah to succeed you as prophet.”— 1 Kings 19:16 (BSB)
