Revelation 13:16-18 And it makes all, the small and the great, and the rich and the poor, and the freemen and the bondmen, that they would give them marks on their right hand, or on their foreheads.

ACV⁽ⁱ⁾ ¹⁶ And it makes all, the small and the great, and the rich and the poor, and the freemen and the bondmen, that they would give them marks on their right hand, or on their foreheads. ¹⁷ And so that not any man can buy or sell unless having the mark-the name of the beast or the number of its name. ¹⁸ Here is wisdom: He who has understanding, let him calculate the number of the beast, for it is a number of a man. And its number is 666.
