Revelation 14:3-5 American Standard Version (ASV)
3 and they sing as it were a new song before the throne, and before the four living creatures and the elders: and no man could learn the song save the hundred and forty and four thousand, even they that had been purchased out of 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 purchased from among men, to be the first-fruits unto God and unto the Lamb. 5 And in their mouth was found no lie: they are without blemish.
