Neither shall there be cut off from the priests, etc....

33:21. Also my covenant with David my servant may be made void, that he should not have a son to reign upon his throne, and with the Levites and priests my ministers.
33:22. As the stars of heaven cannot be numbered, nor the sand of the sea be measured: so will I multiply the seed of David my servant, and the Levites my ministers.
33:23. And the word of the Lord came to Jeremias, saying:
