Luke 1:33
And he will reign over Jacob's descendants forever; his kingdom will never end — the reign over Jacob's descendants forever is the restatement of the eternal Davidic kingdom in terms of Israel's whole family (Jacob/Israel). His kingdom will never end (ouk estai telos, there will not be an end) is the absolute form of the promise — the Davidic kingdom of 2 Samuel 7 that history seemed to terminate in 587 BCE with Babylon's destruction of Jerusalem is now reestablished in a form that cannot be ended.
