Jeremiah 33:21-22

LITV(i) 21 then My covenant with My servant David may also be broken, that he should not have a son to reign on his throne, and with the Levitical priests, My ministers. 22 As the host of the heavens cannot be numbered, nor the sand of the sea measured, so I will multiply the seed of My servant David, and the Levites who minister to Me.
