Revelation 13:15-18

New American Standard Bible

¹⁵ And it was given to him to give breath to the image of the beast, so that the image of the beast would even ^[a]speak and cause ^(A)all who do not ^(B)worship the image of the beast to be killed. ¹⁶ And he causes all, ^(C)the small and the great, the rich and the poor, and the free and the slaves, ^[b]to be given a ^(D)mark on their right hands or on their foreheads, ¹⁷ and he decrees that no one will be able to buy or to sell, except the one who has the ^(E)mark, either ^(F)the name of the beast or ^(G)the number of his name. ^18 (H)Here is wisdom. Let him who has understanding calculate the number of the beast, for the number is that ^(I)of a ^[c]man; and his number is ^[d]six hundred and sixty-six.
