Revelation 13:15-18

Lamsa(i) 15 And he had power to give life to the image of the wild beast, and to cause all those who would not worship the image of the wild beast to be killed. 16 And he compelled all, both small and great, rich and poor, freemen and slaves to receive a mark on their right hands or on their brows: 17 So that no man might buy or sell, except he who had the mark of the name of the beast, or the code number of his name. 18 Here is wisdom. Let him who has understanding decipher the code number of the beast: for it is the code number of the name of a man; and his number is six hundred sixty-six (Nero Caesar).
