Jeremiah 33:17-21

King James Version

¹⁷ For thus saith the Lord; David shall never want a man to sit upon the throne of the house of Israel;

¹⁸ Neither shall the priests the Levites want a man before me to offer burnt offerings, and to kindle meat offerings, and to do sacrifice continually.

¹⁹ And the word of the Lord came unto Jeremiah, saying,

²⁰ Thus saith the Lord; If ye can break my covenant of the day, and my covenant of the night, and that there should not be day and night in their season;

²¹ Then may also my covenant be broken with David my servant, that he should not have a son to reign upon his throne; and with the Levites the priests, my ministers.
