And there were men passing by who saw the body lying in the road with the lion standing beside it, and they went and reported this in the city where the old prophet lived.

1 Kings 13:11
Now a certain old prophet was living in Bethel, and his sons came and told him all the deeds that the man of God had done that day in Bethel. They also told their father the words that the man had spoken to the king.

1 Kings 13:26
When the prophet who had brought him back from his journey heard this, he said, "It is the man of God who disobeyed the command of the LORD. Therefore the LORD has delivered him to the lion, and it has mauled him and killed him, according to the word that the LORD had spoken to him."

And, behold, men passed by, and saw the carcass cast in the way, and the lion standing by the carcass: and they came and told it in the city where the old prophet dwelled.
