Revelation 14:3-5

"...........the hundred and forty and four thousand, which were redeemed from the earth.4 These are they which were not defiled with women; for they are virgins. These are they which 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."
