21 could my covenant with my servant David and my covenant with the Levites ever be broken. So David will by all means always have a descendant to occupy his throne as king and the Levites will by all means always have priests who will minister before me.

Darby

21 [then] shall 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.

KJV

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.
