Rev 13:16 ESV - Also 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,


You will find most all of the modern translation say the the mark will be "ON" the right hand and forehead.

One possibility to consider is that the mark may not be some form of tattoo, barcode, or device placed ON the hand or forehead.  Could these modern, new-age, one-world so-called bibles be preparing people for a mark that would instead be IN their hand or forehead?

Since they are expecting something to be "on" their hand or forehead, would they be willing to accept an implanted device, injected serum, or something that changes DNA?
