Jeremiah 33:19-26 ASV
And the word of Jehovah came unto Jeremiah, saying, Thus saith Jehovah: If ye can break my covenant of the day, and my covenant of the night, so that there shall not be day and night in their season; then may also my covenant be broken with David my servant, that he shall not have a son to reign upon his throne; and with the Levites the priests, my ministers. 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.
And the word of Jehovah came to Jeremiah, saying, Considerest thou not what this people have spoken, saying, The two families which Jehovah did choose, he hath cast them off? thus do they despise my people, that they should be no more a nation before them. Thus saith Jehovah: If my covenant of day and night stand not, if I have not appointed the ordinances of heaven and earth; then will I also cast away the seed of Jacob, and of David my servant, so that I will not take of his seed to be rulers over the seed of Abraham, Isaac, and Jacob: for I will cause their captivity to return, and will have mercy on them.
