Hisgalus 2:17

The one having an ear let him hear what the Ruach Hakodesh says to the Kehillot. To the one who wins the nitzachon (victory), I will give him some of the Manna having been nistar (hidden), and I will give him an even levanah (a white stone) and upon it a Shem Chadash (New Name), of which no one has da'as, except the one receiving it.
