1 Kings 13:9

My refusal of thy favour is not from any contempt or hatred of thy person, but in obedience to the just command of my God, who hath forbidden me all further converse or communication with thee. Eat no bread, nor drink water, to wit, in that place, or with that people; whereby God declares how detestable they were in God's eyes; not because their idolatry was so bad as that of the heathens, but because they were vile apostates from the true God, and embraced this idolworship against the light of their own consciences, merely to comply with the king's humour and command; and because their vicinity and relation to the tribe of Judah made this more dangerous, as to their infection by it. Nor turn again by the same way that thou camest; that by thy avoiding the way that led thee to Beth-el as execrable, although thou wentest by my special command, thou mightest teach all others how much they should abhor that way, and all thoughts of going to that place, or to such people, upon any trivial and unnecessary occasion.
