19. And the word of the Lord came to Jeremiah, saying:
20. "Thus says the Lord: If my covenant with the day is able to be nullified, or my covenant with the night, such that there would be no day and no night in their time,
21. then, too, my covenant with David, my servant, may be nullified, such that he would not have a son who reigns upon his throne, with both the Levites and the priests as my ministers.
