Revelation 14:1-4

1Then I looked, and here was the Lamb standing on Mount Zion, and with him were one hundred and forty-four thousand, who had his name and his Father’s name written on their foreheads.

2I also heard a sound coming out of heaven like the sound of many waters and like the sound of loud thunder. Now the sound I heard was like that made by harpists playing their harps,

3and they were singing a new song before the throne and before the four living creatures and the elders. No one was able to learn the song except the one hundred and forty-four thousand who had been redeemed from the earth.

4These are the ones who have not defiled themselves with women, for they are virgins. These are the ones who follow the Lamb wherever he goes. These were redeemed from humanity as firstfruits to God and to the Lamb,
