Moses and Aaron among his priests, &c. Or, with his princes, as the Hebrew, בכהניו, may be rendered, or his chiefs; that is, his principal and most famous ministers. Moses, however, might with propriety be ranked among the priests, because, before the institution of the priesthood, he executed that office, and because he often interceded with God for the people; which was a very considerable part of the priests' work. And Samuel Who used frequently and solemnly to intercede with God on behalf of the people. The meaning is, “Thus did Moses, and Aaron, and Samuel also, one of the greatest of those prophets who were wont to intercede for you.” Thus he urges them to perform the duty of praising and worshipping God, by the examples of three most eminent persons, who practised this duty with happy success.
