Jeremiah 33:19-22

19The word of the Lord came to Jeremiah:

20"Thus says the Lord: If you can break my covenant with the day and my covenant with the night, so that day and night will not come at their appointed time,

21then also my covenant with David my servant may be broken, so that he shall not have a son to reign on his throne, and my covenant with the Levitical priests my ministers.

22As the host of heaven cannot be numbered and the sands of the sea cannot be measured, so I will multiply the offspring of David my servant, and the Levitical priests who minister to me."
