Revelation 14:3-5 Darby Translation (DARBY)
3 and they sing a new song before the throne, and before the four living creatures and the elders. And no one could learn that song save the hundred [and] forty-four thousand who were bought from the earth.
4 These are they who have not been defiled with women, for they are virgins: these are they who follow the Lamb wheresoever it goes. These have been bought from men [as] first-fruits to God and to the Lamb:
5 and in their mouths was no lie found; [for] they are blameless.
Revelation 14:3-5 New International Version (NIV)
3 And they sang a new song before the throne and before the four living creatures and the elders. No one could learn the song except the 144,000 who had been redeemed from the earth. 4 These are those who did not defile themselves with women, for they remained virgins. They follow the Lamb wherever he goes. They were purchased from among mankind and offered as firstfruits to God and the Lamb. 5 No lie was found in their mouths; they are blameless.
