Jeremiah 33:14-21

14Behold, the days come, saith Jehovah, that I will perform that good word which I have spoken concerning the house of Israel and concerning the house of Judah. 15In 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. 16In those days shall Judah be saved, and Jerusalem shall dwell safely; and this is the name whereby she shall be called: Jehovah our righteousness. 17For thus saith Jehovah: David shall never want a man to sit upon the throne of the house of Israel; 18neither shall the priests the Levites want a man before me to offer burnt-offerings, and to burn meal-offerings, and to do sacrifice continually.

19And the word of Jehovah came unto Jeremiah, saying, 20Thus 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; 21then 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.
