Revelation 13:16-18

International Standard Version

¹⁶ The second beast^[a] forces all people—important and unimportant, rich and poor, free and slaves—to be marked on their right hands or on their foreheads, ¹⁷ so that no one may buy or sell unless he has the mark, which is the beast’s name or the number of its name.

¹⁸ In this case wisdom is needed: Let the person who has understanding^[b] calculate^[c] the total^[d] of the beast, since it is a human multitude,^[e] and the sum of the multitude^[f] is 600, 60, and six.^[g]
