Revelation 13:16-14:1

New International Version

¹⁶ It also forced all people, great and small,^(A) rich and poor, free and slave, to receive a mark on their right hands or on their foreheads,^{(B) 17} so that they could not buy or sell unless they had the mark,^(C) which is the name of the beast or the number of its name.^(D)

¹⁸ This calls for wisdom.^(E) Let the person who has insight calculate the number of the beast, for it is the number of a man.^[a](F) That number is 666.

The Lamb and the 144,000

14 Then I looked, and there before me was the Lamb,^(G) standing on Mount Zion,^(H) and with him 144,000^(I) who had his name and his Father’s name^(J) written on their foreheads.^(K)
