Adam Clarke on 1 Kings 20:36

A lion found him, and slew him - This seems a hard measure, but there was ample reason for it. This person was also one of the sons of the prophets, and he knew that God frequently delivered his counsels in this way, and should have immediately obeyed; for the smiting could have had no evil in it when God commanded it, and it could be no outrage or injury to his fellow when he himself required him to do it.
