C. F. Keil and Franz Delitzsch on 1 Kings 19:19

1Ki 19:19 Call of Elisha to be a prophet. - 1Ki 19:19. As he went thence (viz., away from Horeb), Elijah found Elisha the son of Shaphat at Abel-Meholah, in the Jordan valley (see at Jdg 7:22), occupied in ploughing; “twelve yoke of oxen before him, and he himself with the twelfth” (a very wealthy man therefore), and threw his cloak to him as he passed by. The prophet’s cloak was sign of the prophet’s vocation so that throwing it to him was a symbol of the call to the prophetic office.
