Charles Ellicott Commentary 1 Kings 13:26

"And when the prophet that brought him back from the way heard thereof, he said, It is the man of God, who was disobedient unto the mouth of Jehovah: therefore Jehovah hath delivered him unto the lion, which hath torn him, and slain him, according to the word of Jehovah, which he spake unto him." — 1 Kings 13:26 (ASV)

He said, It is the man of God. —The old prophet did not know how his prediction was to be fulfilled, but recognised at once its supernatural fulfilment. There is in his words a characteristic reticence as to his own share in the work, in respect both of the deceit and the prediction of judgment, perhaps indicating something of the strange mixture of remorse and unscrupulous policy which comes out in his later action.
