Revelation 14:3-4

New International Version

³ And they sang a new song^(A) before the throne and before the four living creatures^(B) and the elders.^(C) No one could learn the song except the 144,000^(D) who had been redeemed from the earth. ⁴ These are those who did not defile themselves with women, for they remained virgins.^(E) They follow the Lamb wherever he goes.^(F) They were purchased from among mankind^(G) and offered as firstfruits^(H) to God and the Lamb.
