17 God has made it clear that there will always be a descendant of David ruling the people of Israel 18 and that there will always be Levitical priests on hand to offer burnt offerings, present grain offerings, and carry on the sacrificial worship in my honor.'" 19 God's Message to Jeremiah: 20 "God says, 'If my covenant with day and my covenant with night ever fell apart so that day and night became haphazard and you never knew which was coming and when, 21 then and only then would my covenant with my servant David fall apart and his descendants no longer rule. The same goes for the Levitical priests who serve me.

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.
