Living_Oracles⁽ⁱ⁾ ³ And they sang a new song before the throne, and before the four living creatures and the elders: and none could learn the song, unless the one hundred and forty-four thousand who are redeemed from the earth. ⁴ These are they who have not been polluted with women; for they are virgins. These are they who follow the Lamb whithersoever he goes. These were redeemed from among men, as the first fruits to God, and to the Lamb. ⁵ And no deceit was found in their mouth; for they are blameless.
