“Here is the wisdom! He who is having the understanding, let him count the number of the beast, for it is the number of a man, and its number: six hundred sixty-six.”— Revelation 13:18 (LSV)
15and there was given to it to give a spirit to the image of the beast, that also the image of the beast may speak, and it may cause as many as will not worship the image of the beast, that they may be killed.
16And it makes all, the small, and the great, and the rich, and the poor, and the freemen, and the servants, that it may give to them a mark on their right hand or on their foreheads,
17and that no one may be able to buy, or to sell, except he who is having the mark, or the name of the beast, or the number of his name.
18Here is the wisdom! He who is having the understanding, let him count the number of the beast, for it is the number of a man, and its number: six hundred sixty-six.
