Revelation 14:1-5

Then I looked. The Lamb was standing on Mount Zion and with Him one hundred and forty-four thousand having His Father’s name written on their foreheads. And I heard a sound from heaven, like the sound of many waters and like the sound of a great thunder. I heard the sound of harpists playing their harps. They sang a new song before the throne and before the four living creatures and the elders. No one could learn that song except the one hundred and forty-four thousand who were redeemed from the earth. These are those who were not defiled with women, for they are virgins. These are those who follow the Lamb wherever He goes. These were redeemed from among men, as first fruits to God and to the Lamb. No lie was found in their mouths, for they are without fault before the throne of God.
