Jeremiah 33:19-22

19And the word of Adonai came to Jeremiah, saying,

20thus says Adonai: “If you can break My covenant with the day and My covenant with the night, so that day and night would not be at in their appointed time,

21only then may My covenant be broken with My servant David, that he would not have a son to reign on his throne, and the Levitical kohanim would not be My ministers.

22As the host of heaven cannot be numbered, nor the sand of the sea measured, so I will multiply the offspring of David My servant, and the Levites who minister to Me.”
