In 1 Kings 20, what happened to a man who refused to smite a prophet when the prophet asked him to do so?

He was killed by a lion

And a certain man of the sons of the prophets said unto his neighbour in the word of the LORD, Smite me, I pray thee. And the man refused to smite him.

Then said he unto him, Because thou hast not obeyed the voice of the LORD, behold, as soon as thou art departed from me, a lion shall slay thee. And as soon as he was departed from him, a lion found him, and slew him. 1 Kings 20:35-36
