Its my understanding that the Mark Of the beast worn on either the hand or the head....refers to that which we DO....the hand and that which we THINK ....the head.
we do well to remember the symbolic nature of ancient hebrew speech
Phylacteries...Keeping God’s law near our eyes....physically
The mindset that had Tefillin, or phylacteries, two small black leather boxes worn on the left arm and forehead by observant adult male Jews.
I believe there to be a substantial analogy there.
I could be wrong.
wow- first time I read this explained differently. Love the analogy.
