REV 2:17

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.
