Revelation 13:15-18

Christian Standard Bible Anglicised

¹⁵ It was permitted to give breath^[a] to the image of the beast, so that the image of the beast could both speak and cause whoever would not worship the image of the beast to be killed.^{(A) 16} And it makes everyone – small and great, rich and poor, free and slave –  receive a mark on his right hand or on his forehead,^{(B) 17} so that no one can buy or sell unless he has the mark: the beast’s name or the number of its name.

¹⁸ This calls for wisdom:^[b](C) Let the one who has understanding calculate^[c] the number of the beast, because it is the number of a person. Its number is 666.^[d]
