John Gill Commentary 1 Kings 13:24

"And when he was gone, a lion met him by the way, and slew him: and his body was cast in the way, and the ass stood by it; the lion also stood by the body." — 1 Kings 13:24 (ASV)

And when he was gone, a lion met him by the way, and slew him , &c.] Perhaps not far from Bethel; and this lion might come out of the same wood the she bears did, that devoured the children that mocked the prophet, as Bishop Patrick conjectures, (2 Kings 2:23 2 Kings 2:24)

and his carcass was cast in the way ; in the high road, where it seems the lion seized him, and he fell:

and the ass stood by it ; disregarded and unhurt by the lion, though the prophet was pulled off of the back of him:

the lion also stood by the carcass : not offering to tear it in pieces and devour it, but rather, as if he was the guard of it, to keep off all others from meddling with it; these circumstances are very surprising, and show the thing to be of God; for when the lion had done what he had a commission to do, which was to kill the prophet, he was to do no more.
