“Afterwards, King Manasseh built an outer wall for the city of David west of Gihon, in the valley, reaching the entrance at the Fish Gate. He carried it around the Ophel. He raised it to a very great height. He also put commanders of the army in all the fortified cities in Judah. He took away the foreign gods and the idol from the house of Yahweh. He threw all the altars that he had built on the mountain of the house of Yahweh and in Jerusalem outside of the city. He also restored the altar of Yahweh. He offered on it sacrifices of well-being and of thanksgiving. He commanded Judah to serve Yahweh the God of Israel. Nevertheless, the people still sacrificed at the high places, but only to Yahweh their God.”
King Manasseh fortified the city of David and the various cities of Judah. This new wall went around to Gihon and Ophel, at the Fish Gate on the northwest side of Jerusalem. This had to do with the water and the fish markets. More importantly, he got rid of the foreign gods that he placed in and around the Temple. He tore down the altars of the other gods. He took the idol out of the Temple. He restored the altar to Yahweh. He himself offered sacrifices of well-being and thanksgiving. He wanted everyone to be Yahweh worshippers. However, they still sacrificed at the high places, but only to Yahweh and not other gods.
