1 Kings 13:7-9

7Then the king said to the man of God, “Come home with me and refresh yourself, and I will give you a reward.”

8But the man of God said to the king, “If you were to give me half your house, I would not go in with you; nor would I eat bread nor drink water in this place.

9For so it was commanded me by the word of the Lord, saying, ‘You shall not eat bread, nor drink water, nor return by the same way you came.’ ”
