Jeremiah 33:19

17For the LORD says: “David will never lack a man to sit on the throne of the house of Israel.

18The Levitical priests won’t lack a man before me to offer burnt offerings, to burn meal offerings, and to do sacrifice continually.”

19The LORD’s word came to Jeremiah, saying,

20“The LORD says: ‘If you can break my covenant of the day and my covenant of the night, so that there will not be day and night in their time,

21then my covenant could also be broken with David my servant, that he won’t have a son to reign on his throne; and with the Levitical priests, my ministers.
