33:14-26 To crown the blessings God has in store, here is a promise of the Messiah. He imparts righteousness to his church, for he is made of God to us righteousness; and believers are made the righteousness of God in him. Christ is our Lord God, our righteousness, our sanctification, and our redemption. His kingdom is an everlasting kingdom. But in this world prosperity and adversity succeed each other, as light and darkness, day and night. The covenant of priesthood shall be secured. And all true believers are a holy priesthood, a royal priesthood, they offer up spiritual sacrifices, acceptable to God; themselves, in the first place, as living sacrifices. The promises of that covenant shall have full accomplishment in the gospel Israel. In Ga 6:16, all that walk according to the gospel rule, are made to be the Israel of God, on whom shall be peace and mercy. Let us not despise the families which were of old the chosen people of God, though for a time they seem to be cast off.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.
