Jeremiah 33:15-22

In those days, and at that time, will I cause a Branch of righteousness to grow up unto David; and he shall execute justice and righteousness in the land. In those days shall Judah be saved, and Jerusalem shall dwell safely; and this is the name whereby she shall be called: Jehovah our righteousness. For thus saith Jehovah: David shall never want a man to sit upon the throne of the house of Israel; neither shall the priests the Levites want a man before me to offer burnt-offerings, and to burn meal-offerings, and to do sacrifice continually. 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.
