Revelation 13:15-18

AUV(i) 15 Now the [second] beast was given [the power] to give breath to the statue of the [first] beast, so that it could both speak and cause all those who refused to worship the statue of the [first] beast to be killed. 16 And this second beast forced everyone to be branded with a mark on their right hand and on their forehead --- insignificant and important people, rich and poor people, and free people and slaves --- 17 so that no one would be able to buy or sell things without having the mark, either the name of the [first] beast or the number of his name. 18 This calls for wisdom; the person who has understanding should calculate the number of the beast, for it is the number of a person. And his number is six hundred and sixty-six.
