Jeremiah 33:21-22

21then My covenant may also be broken with David My servant so that he will not have a son to reign on his throne, and [My covenant may also be broken] with the Levitical priests, My ministers.

22As the host of [the stars of] heaven cannot be counted and the sand of the sea cannot be measured, so I will multiply the descendants of David My servant and the Levites who minister to Me.’ ”
