Jeremiah 33:21
Then may also my covenant be broken with David my servant, that he should not have a son to reign upon his throne; and with the Levites the priests, my ministers.
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 Psalms 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.
