Dear Rabbi Simon,
Will King David return?
King David’s descendant will redeem the Jewish People and indeed all mankind. This is Mashiach ben David whose arrival we continue to await. The doctrine of the Resurrection of the Dead in messianic times implies that King David, together with the righteous of all generations, will indeed “return”, however our world will have already been substantially transformed by then.
So no, in the first instance we await the arrival of the messiah, a descendant of David and Solomon, not of King David himself.
Speedily in our days.
Rabbi Rashi Simon
