Jeremiah 33:21-26 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 .
22 As the host of heaven cannot be numbered , neither the sand of the sea measured : so will I multiply the seed of David my servant, and the Levites that minister unto me.
23 Moreover the word of the LORD came to Jeremiah, saying ,
24 Considerest thou not what this people have spoken , saying , The two families which the LORD hath chosen , he hath even cast them off ? thus they have despised my people, that they should be no more a nation before them.
25 Thus saith the LORD; If my covenant be not with day and night, and if I have not appointed the ordinances of heaven and earth;
26 Then will I cast away the seed of Jacob, and David my servant, so that I will not take any of his seed to be rulers over the seed of Abraham, Isaac, and Jacob: for I will cause their captivity to return , and have mercy on them.
