John Gill Commentary 2 Chronicles 24:18

"And they forsook the house of Jehovah, the God of their fathers, and served the Asherim and the idols: and wrath came upon Judah and Jerusalem for this their guiltiness." — 2 Chronicles 24:18 (ASV)

And they left the house of the Lord God of their fathers
Came no more to the temple at Jerusalem, forsook the worship and service of it:

and served groves and idols ;
worshipped idols in groves, which were upon high places:

and wrath came upon Judah and Jerusalem for this their trespass :
their idolatry, and particularly on these princes, the Syrian army coming against them, and destroying them, (2 Chronicles 24:23) .
