Kabbalah su Salmi 57:9

(Because of this) King David lives on forever. Even during the Days of King Messiah, he remains the king. For we have learned that if Messiah shall be from among the living, David will be his name. And if he shall be from among (the resurrected souls of) the deceased, David shall be his name. And he shall arouse the dawn before he arrives. It is written, "Awake, my glory; awake the harp and the lyre; I will awake the dawn" (Ps. 57:9).
