Thematic Bible: Alone can learn the songs of heaven

They sang a new song before the throne and before the four living creatures and the elders, but no one could learn the song except the 144,000 who had been redeemed from the earth. These are the ones not defiled with women, for they have kept their virginity. These are the ones who follow the Lamb wherever He goes. They were redeemed from the human race as the firstfruits for God and the Lamb.
