Charles Spurgeon Commentary 2 Chronicles 33:4-5

"And he built altars in the house of Jehovah, whereof Jehovah said, In Jerusalem shall my name be for ever. And he built altars for all the host of heaven in the two courts of the house of Jehovah." — 2 Chronicles 33:4-5 (ASV)

Also he built altars in the house of the LORD, whereof the LORD had said, In Jerusalem shall my name be for ever. And he built altars for all the host of heaven in the two courts of the house of the LORD.

There was plenty of room elsewhere for them if Manasseh wanted them; but nothing would do for him but that in the house of God itself must be built altars for the worship of the sun and all the host of stars.
