Davidic dynasty in Bible prophecy

(2 Kings 25:27–30) His family retained leadership of the Babylonian exiles (Ezekiel 1:2), and his descendants were at the head of those who returned to Zion.

The destruction of the Kingdom of Judah by Nebuchadnezzar in 586 BCE brought an end to the rule of the royal house of David.

They argue the presence of both unconditional and conditional promises to the house of David would create intense theological dissonance in the Book of Kings.

[7][8][9][10] Christians believe that the promise is for the coming one who would fulfill the role of king and priest, which they state Jesus did, rather than a permanent earthly kingship.

God did not promise an unbroken monarchy but one of David's descendants who would be qualified to sit on that throne when it was reestablished.

and in the context of "those days" coming in the future, then says 17 "For this is what the LORD says: David will never fail to have a man sitting on the throne of the house of Israel."

So the context in the text clearly states this promise being for the future “coming” Davidic fulfillment, not for an unbroken line of descendants and in the typical Old Testament prophets language of hyperbole, Jesus fulfilled the King and Priest role as a priest according to the line of Melchizedek in Gen 14:18 “ Melchizedek, king of Salem, brought out bread and wine; he was a priest to God Most High.” David’s earthly line failed before the righteous Branch came, hence Jeremiahs future prophesy.

In Luke's days they argue, it was proper and correct to cite Joseph's name in Mary's genealogy.

[15] Moreover, Jews argue that the Messiah must descend through David's son Solomon (2 Sam 7:12–16, Psalm 89:28–38, 1 Chronicles 17:11–14, 22:9–10, 28:6–7).

In addition, to presume that Mary was of Davidic descent in Luke presents the problem that Mary could not pass on what she did not possess: (1) Maternal connection does not enter into consideration for succession to the throne of David which is passed on only through a continuous male line: "There shall not be cut off from David a man to sit upon the throne of the house of Israel" (Jeremiah 33:17); (2) Biblically, the right of lineal privilege, that is, kingship and priesthood, are exclusively passed on through the male line.
