Revelation 14:3-4 And they sung as it were a new song before the throne, and before the four beasts, and the elders: and no man could learn that song but the hundred and forty and four thousand, which were redeemed from the earth.

KJC⁽ⁱ⁾ ³ And they sung as it were a new song before the throne, and before the four beasts, and the elders: and no man could learn that song but 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 wherever he goes. These were redeemed from among men, being the first fruits unto God and to the Lamb.
