What does 1 Kings 13:19 mean?

He said, “I may not return with you, nor go in with you. I will not eat bread or drink water with you in this place.

For it was said to me by Yahweh’s word, ‘You shall eat no bread or drink water there, and don’t turn again to go by the way that you came.’”

He said to him, “I also am a prophet as you are; and an angel spoke to me by Yahweh’s word, saying, ‘Bring him back with you into your house, that he may eat bread and drink water.’” He lied to him.

As they sat at the table, Yahweh’s word came to the prophet who brought him back;

and he cried out to the man of God who came from Judah, saying, “Yahweh says, ‘Because you have been disobedient to Yahweh’s mouth, and have not kept the commandment which Yahweh your God commanded you,

but came back, and have eaten bread and drank water in the place of which he said to you, “Eat no bread, and drink no water”; your body will not come to the tomb of your fathers.’”
