Amos 7:11 (KJV)

The LORD repented for this: This also shall not be, saith the Lord GOD.

Thus he shewed me: and, behold, the LORD stood upon a wall made by a plumbline, with a plumbline in his hand.

And the LORD said unto me, Amos, what seest thou? And I said, A plumbline. Then said the LORD, Behold, I will set a plumbline in the midst of my people Israel: I will not again pass by them any more:

And the high places of Isaac shall be desolate, and the sanctuaries of Israel shall be laid waste; and I will rise against the house of Jeroboam with the sword.

Then Amaziah the priest of Bethel sent to Jeroboam king of Israel, saying, Amos hath conspired against thee in the midst of the house of Israel: the land is not able to bear all his words.

Also Amaziah said unto Amos, O thou seer, go, flee thee away into the land of Judah, and there eat bread, and prophesy there:

But prophesy not again any more at Bethel: for it is the king's chapel, and it is the king's court.

Then answered Amos, and said to Amaziah, I was no prophet, neither was I a prophet's son; but I was an herdman, and a gatherer of sycomore 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, Prophesy not against Israel, and drop not thy word against the house of Isaac.
