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, so 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.
