Jeremiah 33:17-26 (NKJV)
17 “For thus says the Lord: ‘David shall never lack a man to sit on the throne of the house of Israel; 18 nor shall the priests, the Levites, lack a man to offer burnt offerings before Me, to [d]kindle grain offerings, and to sacrifice continually.’ ”
The Permanence of God’s Covenant
19 And the word of the Lord came to Jeremiah, saying, 20 “Thus says the Lord: ‘If you can break My covenant with the day and My covenant with the night, so that there will not be day and night in their season, 21 then My covenant may also be broken with David My servant, so that he shall not have a son to reign on his throne, and with the Levites, the priests, My ministers. 22 As the host of heaven cannot be numbered, nor the sand of the sea measured, so will I multiply the descendants of David My servant and the Levites who minister to Me.’ ”
23 Moreover the word of the Lord came to Jeremiah, saying, 24 “Have you not considered what these people have spoken, saying, ‘The two families which the Lord has chosen, He has also cast them off’? Thus they have despised My people, as if they should no more be a nation before them.
25 “Thus says the Lord: ‘If My covenant is not with day and night, and if I have not appointed the ordinances of heaven and earth, 26 then I will cast away the descendants of Jacob and David My servant, so that I will not take any of his descendants to be rulers over the descendants of Abraham, Isaac, and Jacob. For I will cause their captives to return, and will have mercy on them.’ ”
