Revelation 13:16-18
New American Standard Bible
Chapter 13
16And he causes all, the small and the great, the rich and the poor, and the free and the slaves, to be given a mark on their right hands or on their foreheads, 17and he decrees that no one will be able to buy or to sell, except the one who has the mark, either the name of the beast or the number of his name. 18Here is wisdom. Let him who has understanding calculate the number of the beast, for the number is that of a man; and his number is six hundred and sixty-six.King James Version
Chapter 13
16And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: 17And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name. 18Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six.Christian Standard Bible
New Living Translation
Chapter 13
16He required everyone — small and great, rich and poor, free and slave — to be given a mark on the right hand or on the forehead. 17And no one could buy or sell anything without that mark, which was either the name of the beast or the number representing his name. 18Wisdom is needed here. Let the one with understanding solve the meaning of the number of the beast, for it is the number of a man. His number is 666.English Standard Version
Chapter 13
16Also it causes all, both small and great, both rich and poor, both free and slave, to be marked on the right hand or the forehead, 17so that no one can buy or sell unless he has the mark, that is, the name of the beast or the number of its name. 18This calls for wisdom: let the one who has understanding calculate the number of the beast, for it is the number of a man, and his number is 666.New International Version
