Adam Clarke's Commentary on the Bible

Verse 15 (2 Chronicles 11:15)

And he ordained him priests - for the devils - שעירים seirim , the hairy ones; probably goats: for as the golden calves, or oxen, were in imitation of the Egyptian ox-god, Apis; so they no doubt paid Divine honors to the goat, which we know was an object of religious veneration in Egypt.
