(Revelation 13:16-17) “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.”

It is interesting, that in verse 16, there are 6 types of people who receive the mark in their hand.
