Revelation 14:2-4

Revised Geneva Translation

² And I heard a voice from Heaven, as the sound of many waters, and as the sound of a great thunder. And I heard the voice of harpists, harping with their harps.

³ And they sang (as it were) a new song before the throne, and before the four beasts and the elders. And no one could learn that song except the 144,000 who were bought from the earth.

⁴ These are those who are not defiled with women, for they are virgins. These follow the Lamb wherever He goes. These are bought from man, being the firstfruits to God and to the Lamb.
