Charles Spurgeon Commentary 2 Chronicles 33:3

"For he built again the high places which Hezekiah his father had broken down; and he reared up altars for the Baalim, and made Asheroth, and worshipped all the host of heaven, and served them." — 2 Chronicles 33:3 (ASV)

For he built again the high places which Hezekiah his father had broken down,

These high places were at first built for the worship of God, the true God; but then the law of Jehovah was that there should be only one altar, namely, that at Jerusalem. This was not Popery, but Ritualism; it was adding something to the simple worship of God, and therefore it was wrong.

He who goes a little way in sin will soon go a long way. It is always a mercy to stop where you ought to stop, and not begin going down.

Hezekiah had broken down the high places, and his son Manasseh rebuilt them.

And he reared up altars for Baalim, and made groves, and worshipped all the host of heaven, and served them.

He not only worshipped them, but he served them; he threw his whole strength into the propagation of this form of idolatry. Those who build altars to God, contrary to the Lord's law, will soon have false gods. First, people set up images to remind them of the true God; and then they go off to the worship of the idols, or false gods. Oh, may we have grace to make no likeness of the Lord, and to set up nothing contrary to the simple teaching of the Word of God!

For he built again the high places which Hezekiah his father had broken down, and he reared up altars for Baalim, and made groves, and worshipped all the host of heaven, and served them.

One form of idolatry was not enough for him; he must have all forms of it, even rearing altars to Baal, and making the stars also to be his gods.
