16 And 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: 17 And 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.

Revelation 14:9-11 New Living Translation (NLT) Then a third angel followed them, shouting, "Anyone who worships the beast and his statue or who accepts his mark on the forehead or on the hand must drink the wine of God’s anger. It has been poured full strength into God’s cup of wrath. And they will be tormented with fire and burning sulfur in the presence of the holy angels and the Lamb. The smoke of their torment will rise forever and ever, and they will have no relief day or night, for they have worshiped the beast and his statue and have accepted the mark of his name."
