Jeremiah 33:20,21

If you can break my covenant of the day and of the night Called the ordinances of the day and night, Jeremiah 31:35. Then may also my covenant be broken with David and with the Levites A promise this, that the kingdom of Christ and a Christian ministry shall continue in the church to the end of time. And as his kingdom shall have no end, (Luke 1:32,) the words may also be construed as extending to the eternal state, in which, as Christ shall reign in glory for ever, so his saints shall be priests unto God, and reign for ever with him.
