Jeremiah 33:14-18 New Revised Standard Version (NRSV)
The Righteous Branch and the Covenant with David
14 The days are surely coming, says the Lord, when I will fulfill the promise I made to the house of Israel and the house of Judah. 15 In those days and at that time I will cause a righteous Branch to spring up for David; and he shall execute justice and righteousness in the land. 16 In those days Judah will be saved and Jerusalem will live in safety. And this is the name by which it will be called: “The Lord is our righteousness.”
17 For thus says the Lord: David shall never lack a man to sit on the throne of the house of Israel, 18 and the levitical priests shall never lack a man in my presence to offer burnt offerings, to make grain offerings, and to make sacrifices for all time.
