O give thanks unto the God of gods: for his mercy endureth for ever. The God of gods - לאדני האדנים ladonai haadonim. As adonai signifies director, etc., it may apply here, not to idols, for God is not their god; but to the priests and spiritual rulers; as Lord of lords may apply to kings and magistrates, etc. He is God and ruler over all the rulers of the earth, whether in things sacred or civil.
