Revelation 13:17-18

English Standard Version

¹⁷ so that no one can buy or sell unless he has the mark, that is, ^(A)the name of the beast or ^(B)the number of its name. ^18 (C)This calls for wisdom: let the one who has understanding calculate the number of the beast, for it is the number ^(D)of a man, and his number is 666.^[a]
