Albert Barnes Commentary 2 Chronicles 11:15

"and he appointed him priests for the high places, and for the he-goats, and for the calves which he had made." — 2 Chronicles 11:15 (ASV)

The high places—that is, the two sanctuaries at Dan and Bethel.

For the devils—literally, “for the goats”: the word is probably used for objects of idolatrous worship in general.
