The fifteenth bracha of Shemoneh Esrei is Malchus Beis David, for the restoration of the Davidic dynasty. The Moshiach (Messiah) will be a descendant of King David and he is referred to as “tzemach David,” “the shoot of David.” (“Shoot” in the botanical sense, like a sprout.) The Radak on our verse explains that a shoot comes into the world alongside many others. Similarly, when the Moshiach reveals himself, the world will be full of comparably righteous people.
