Jeremiah 33:15-18

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.
