John Gill Commentary 2 Chronicles 24:7

"For the sons of Athaliah, that wicked woman, had broken up the house of God; and also all the dedicated things of the house of Jehovah did they bestow upon the Baalim." — 2 Chronicles 24:7 (ASV)

For the sons of Athaliah, that wicked woman
Not Ahaziah and his brethren, in the lifetime of Jehoram, but sons of Athaliah by another man, as Kimchi suggests:

had broken up the house of God ;
not that they had made ruptures in it, or broke down the walls of it, but had defaced it by taking off the gold and silver upon it:

and also all the dedicated things of the house of the Lord did they
bestow upon Baalim ;
not strictly all, but a great many of them, as this word in many instances is used, as Kimchi observes, and with them furnished, beautified, and adorned the temple of Baal.
