Jeremiah 33:14-21

14Behold, the days come, saith the LORD, that I will perform that good thing which I have promised to the house of Israel and to the house of Judah. 15In those days, and at that time, will I cause the Branch of righteousness to grow up to David; and he shall execute judgment and righteousness in the land. 16In those days shall Judah be saved, and Jerusalem shall dwell in safety: and this is the name by which she shall be called, The LORD our righteousness.1

17For thus saith the LORD; David shall never lack a man to sit upon the throne of the house of Israel;2 18Neither shall the priests the Levites lack a man before me to offer burnt offerings, and to kindle meat offerings, and to offer sacrifice continually. 19And the word of the LORD came to Jeremiah, saying, 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.
