1 Kings 13:27

“When the prophet who had brought him back from his journey heard of it, he said, “It is the man of God who defied the word of the Lord. The Lord has given him over to the lion, which has mauled him and killed him, as the word of the Lord had warned him.””

Contextual reference, as this verse is immediately prior and explains why he is bringing the body back.

“The old prophet lifted the body of the man of God, laid it on his own donkey and brought it back to his own town to mourn over him.”

Contextual reference, as this verse is immediately after and describes the burial.

“Then he laid the body in his own tomb, and they mourned over him and said, “Alas, my brother!””

Further context, describing the mourning.

“...you came back and ate food and drank water in the place where he told you not to go, therefore your body will not be buried in the tomb of your ancestors.”

This is the prophecy that is being fulfilled

“After burying him, he said to his sons, “When I die, bury me in the grave with him; lay my bones beside his bones.”

Shows the old prophet's desire to be associated with the man of God, even in death.
