17 "For thus says the Lord , 'David shall never lack a man to sit on the throne of the house of Israel ; 18 and the Levitical priests shall never lack a man before e Me to offer burnt offerings , to burn grain offerings and to prepare sacrifices continually e .' " 19 The word of the Lord came to Jeremiah , saying , 20 "Thus says the Lord , 'If you can break My covenant for the day and My covenant for the night , so that day and night will not be at their appointed time , 21 then My covenant may also be broken with David My servant so that he will not have a son to reign on his throne , and with the Levitical priests , My ministers .

Commentary on Jeremiah 33:14-26
(Read Jeremiah 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 Galatians 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.
