Revelation 14:3-5 21st Century King James Version (KJ21)
3 And they sang, as it were, a new song before the throne, and before the four living beings and the elders; and no man could learn that song, except the hundred and forty and four thousand who were redeemed from the earth.
4 These are they that were not defiled with women, for they are virgins. These are they that follow the Lamb whithersoever He goeth. These were redeemed from among men, being the firstfruits unto God and to the Lamb.
5 And in their mouth was found no guile, for they are without fault before the throne of God.
