The Bible in no way implies that the mark of the beast will be covid masks:
Revelation 13:16
"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:"
Now when we look at this verse first off we see that the mark is "in their" and not "on their" this is implying that it could be inside their right hand/forehead.
Second we see that it can be "in their right hand" which destroys the thought of it ever even being anything remotely close to a mask.
