I’m generally opposed to quotes from that awful fuckin’ book, but context here works.
You won’t be able to buy or sell without the mark of the beast. Think crypto chip.
not yet. soon, buy not quite yet.
Non-Christian and non-Bible person here, but I think it’s probably best to be accurate about citing these things:
Revelation 13:16-17 King James Version
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.
