“so that no one could buy or sell unless he had the mark — the name of the beast or the number of its name.”
Revelation 13:17 (BSB)
Context Reading
15The second beast was permitted to give breath to the image of the first beast, so that the image could speak and cause all who refused to worship it to be killed. 16And the second beast required all people, small and great, rich and poor, free and slave, to receive a mark on their right hand or on their forehead, 17so that no one could buy or sell unless he had the mark — the name of the beast or the number of its name. 18Here is a call for wisdom: Let the one who has insight calculate the number of the beast, for it is the number of a man, and that number is 666.
