Revelation of Yeshua to Yochanan (Rev) 14:1-5

Then I looked, and there was the Lamb standing on Mount Tziyon; and with him were 144,000 who had his name and his Father’s name written on their foreheads. I heard a sound from heaven like the sound of rushing waters and like the sound of pealing thunder; the sound I heard was also like that of harpists playing on their harps. They were singing a new song before the throne and before the four living beings and the elders, and no one could learn the song except the 144,000 who have been ransomed from the world. These are the ones who have not defiled themselves with women, for they are virgins; they follow the Lamb wherever he goes; they have been ransomed from among humanity as firstfruits for God and the Lamb; on their lips no lie was found — they are without defect.
