21 then may also my covenant be broken with David my servant, that he shall not have a son to reign on his throne; and with the Levites the priests, my ministers.

This promise also has been not literally, but spiritually fulfilled, for in this sense only have the seed of David and the Levites been multiplied.
Then may also my covenant be broken with David my servant,.... A type of the Messiah, with whom the covenant of grace is made, stands fast, and will never be broken; see Psalm 89:3; for, as the other is impossible, the breaking of the covenant with day and night, or hindering the certain rotation of them; so likewise as impossible is the breaking of the covenant with David concerning the perpetuity of his kingdom in the Messiah:
that he should not have a son to reign upon his throne; which he has in Christ, and ever will have; for he shall reign for ever and ever:
and with the Levites my priests, my ministers; of the line of Phinehas, to whom an everlasting priesthood was promised, and which has been fulfilled in Christ, who has an unchangeable priesthood; a priesthood that will never pass from him, and go to another; see Numbers 25:13, Hebrews 7:24.
