The Davidic Kingdom

14 ‘Behold, the days are coming,’ says the Lord, ‘when I will fulfill the good word and promise which I have made regarding the house of Israel and the house of Judah. 15 In those days and at that time I will cause a righteous Branch of David to spring forth; and He (the Messiah) shall execute justice and righteousness on the earth.(A) 16 In those days Judah will be saved and [the people of] Jerusalem will live in safety; and this is the name by which she will be called: the Lord Our Righteousness (Justice).’ 17 For thus says the Lord, ‘David shall never lack a man (descendant) to sit on the throne of the house of Israel; 18 and the Levitical priests shall never lack a man (descendant) to offer burnt offerings before Me and to burn grain offerings and to prepare sacrifices all day long.’”
19 The word of the Lord came to Jeremiah, saying, 20 “Thus says the Lord, ‘If you can break My covenant for the day and My covenant for the night, so that day and night do not take place at their appointed times, 21 then My covenant may also be broken with David My servant so that he will not have a son to reign on his throne, and [My covenant may also be broken] with the Levitical priests, My ministers. 22 As the host of [the stars of] heaven cannot be counted and the sand of the sea cannot be measured, so I will multiply the descendants of David My servant and the Levites who minister to Me.’”
23 And the word of the Lord came to Jeremiah, saying, 24 “Have you not noticed what this people have spoken, saying, ‘The two families [Israel the northern kingdom, and Judah the southern kingdom] which the Lord chose, He has rejected’? Thus they despise My [chosen] people, no longer are they [considered] as a nation in their sight. 25 Thus says the Lord, ‘If My covenant with day and night does not stand, and if I have not established the fixed patterns of heaven and earth, [the whole order of nature,] 26 then I would [also] reject the descendants of Jacob and David My servant, not taking from his descendants rulers over the descendants of Abraham, Isaac, and Jacob. But I will restore their fortunes, and will have mercy on them.’”(B)
