Rev 13:16-17
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.
KJV
That doesn’t read much like a parable to me.
Could be a metaphor, too, you know. I know it’s a stretch - it’s not like The Bible has any metaphors in it, you know.
