Jeremiah 33:20

16 In those days Judah will be saved, and Jerusalem will dwell securely, and this is the name by which it will be called: The LORD Our Righteousness.

17 For this is what the LORD says: David will never lack a man to sit on the throne of the house of Israel,

18 nor will the priests who are Levites ever fail to have a man before Me to offer burnt offerings, to burn grain offerings, and to present sacrifices.”

19 And the word of the LORD came to Jeremiah:

20 “This is what the LORD says: If you can break My covenant with the day and My covenant with the night, so that day and night cease to occupy their appointed time,

21 then My covenant may also be broken with David My servant and with My ministers the Levites who are priests, so that David will not have a son to reign on his throne.

22 As the hosts of heaven cannot be counted and as the sand on the seashore cannot be measured, so too will I multiply the descendants of My servant David and the Levites who minister before Me.”

23 Moreover, the word of the LORD came to Jeremiah:

24 “Have you not noticed what these people are saying: ‘The LORD has rejected the two families He had chosen’? So they despise My people and no longer regard them as a nation.
