Jeremiah 33:20-22

King James Version

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.

²² As the host of heaven cannot be numbered, neither the sand of the sea measured: so will I multiply the seed of David my servant, and the Levites that minister unto me.
