2 Kings 16:14
And the brasen altar which had been before the LORD, he caused to be moved in front of the forefront of the house, from between the altar and the house of the LORD, and he put it beside the altar towards the Aquilon.
Then he said unto me, Son of man, lift up thine eyes now the way toward the north. So I lifted up my eyes the way toward the north, and behold northward at the gate of the altar this image of jealousy in the entry.
