Jeremiah 33:20-26

20Thus saith the LORD; If ye can break my covenant of the day, and my covenant of the night, so that there should not be day and night in their season; 21Then also may 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. 22As 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 to me. 23Moreover the word of the LORD came to Jeremiah, saying, 24Considerest 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. 25Thus saith the LORD; If my covenant is not with day and night, and if I have not appointed the ordinances of heaven and earth; 26Then 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 captives to return, and have mercy on them.
