Thematic Bible: Forbidden to prophesy in israel

Then Amaziah the priest of Bethel sent to Jeroboam king of Israel, saying, Amos has conspired against thee in the midst of the house of Israel; the land is not able to bear all his words. For thus hath Amos said, Jeroboam shall die by the sword, and Israel shall surely be led away captive out of their own land. And Amaziah said unto Amos, O thou seer, go, flee thee away into the land of Judah, and eat thy bread there, and prophesy there: read more.
but do not prophesy any more in Bethel: for it is the king's sanctuary, and the head of the kingdom. Then Amos answered and said to Amaziah, I am not a prophet, neither am I a prophet's son, but I am a herdsman and a gatherer of sycamore fruit: and the LORD took me as I followed the flock, and the LORD said unto me, Go, prophesy unto my people Israel. Now therefore hear thou the word of the LORD: Thou sayest, Do not prophesy against Israel and do not drop thy word against the house of Isaac. Therefore thus hath the LORD said; Thy wife shall be a harlot in the city, and thy sons and thy daughters shall fall by the sword, and thy land shall be divided by lots; and thou shalt die in a polluted land; and Israel shall surely go into captivity from his land.
