Charles Spurgeon 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, and served groves and idols:

Or, "Asherah and idols." The word is mistakenly translated "groves." These were certain horrible and disgusting emblems of the heathen goddess Ashtaroth, or Astarte: "They served Asherah and idols."
