2 Kings 21:5

And he built altars for all the host of heaven
Sun, moon, and stars:

in the two courts of the house of the Lord;
in the court of the priests, and in the court of the people; and all this must be supposed to be done, not as soon as he began to reign, but when he was grown up to man's estate, and had children, as the next verse shows; unless it can be thought that those nobles in Judah, who liked not the reformation made by Hezekiah, took the advantage of his youth, and advised him to these idolatries.
