RKJNT⁽ⁱ⁾ ³ And they sang a new song before the throne, and before the four living creatures, and the elders: and no man could learn that song but the hundred and forty-four thousand, who had been redeemed from the earth. ⁴ These are the ones who have not defiled themselves with women; for they are chaste.
