Amaziah also said to Amos, "You seer, go, flee away into the land of Judah, and there eat bread, and prophesy there:
"Eat bread, and prophecy there ..." the implications of this are a gross reflection upon Amaziah himself, as many have pointed out.  He did not recognize any such thing as a truly prophetic office; to him all prophets were concerned merely with what they could get out of it, this being a perfect reflection of his own character.  The argument he makes, to the extent that there is any, is that Judah would pay more for prophecies against Israel than could be received for such prophecies being delivered in Israel itself!  The expression "eat bread" means "make your living," "peddle your wares," or "do your thing" in Judah, and not at Bethel.
