Wherefore the anger of the Lord was kindled against Amaziah,.... Idolatry being always highly displeasing to the Lord; and this was a most provoking instance of it, that when the Lord had given him victory over his enemies, that he should forsake him, and worship their gods: and he sent unto him a prophet; whether the same as before, is not certain: which said unto him, why hast thou sought after the gods of the people which could not deliver their own people out of thine hand? and therefore it was madness in him to seek after them, and worship them.
