Here, as in many psalms of a like nature, is an invitation to praise Jehovah; and the several orders of the people are especially called upon to this service. The house of Aaron is mentioned by name; but perhaps this is in accommodation to gospel times also, when Jesus hath made his people kings and priests unto God and the Father. Every man may find in the history of his own life enough to demand the unceasing tribute of praise. Revelation 1:6.
