And I looked, and, lo, a Lamb stood on mount Zion, and with him a hundred and forty-four thousand, having his Father's name written in their foreheads. And I heard a voice from heaven, as the voice of many waters, and as the voice of a great thunder: and I heard the voice of harpers harping with their harps: And they sung as it were a new song before the throne, and before the four beasts, and the elders:

And no man could learn that song but the hundred and forty-four thousand, who were redeemed from the earth. These are they who were not defiled with women; for they are virgins. These are they who follow the Lamb wherever he goes. These were redeemed from among men, being the first fruits unto God and to the Lamb. And in their mouth was found no guile: for they are without fault before the throne of God. (Revelation 14:1-5)
