Charles Ellicott Commentary 2 Chronicles 28:2

"but he walked in the ways of the kings of Israel, and made also molten images for the Baalim." — 2 Chronicles 28:2 (ASV)

And made also molten images for Baalim. — For the Baals, that is, the different aspects or avatars of the Canaanite god. This clause is added by the chronicler, in explanation of the former one; “the way of the kings of Israel” was the state recognition of Baal worship, side by side with that of Jehovah (2 Chronicles 21:6; 2 Chronicles 22:3–4; compare 2 Chronicles 23:17). But possibly both this and the first clause of 2 Chronicles 28:3 have fallen out of the text of Kings. (So Thenius on that passage.)
