And he left the oxen and ran after Elijah and said, “Let me kiss my father and my mother, and then I will follow you.” And he said to him, “Go back again, for what have I done to you?”
Elisha was named last in the orders God gave to Elijah, but he was first called, for by him the other two were to be called. He must come in Elijah's room; yet Elijah is forward to raise him, and is far from being jealous of his successor, but rejoices to think that he shall leave the work of God in such good hands.
Commenting on 1 Kings 19:19-21
And he left the oxen, and ran after Elijah,.... His heart being touched by the Lord at the same time, and his mind enlightened to understand what was meant by that action: and said, let me, I pray thee, kiss my father and my mother; take his leave of them in this way, which was what was used by friends at parting, see Rut 1:9.
what have I done to thee?--that is, Go, but keep in mind the solemn ceremony I have just performed on thee. It is not I, but God, who calls thee. Do not allow any earthly affection to detain you from obeying His call.
