I think gematria is a different thing then Q posting messages like the one you're talking about, if that was in fact his message (and it could be).
That gematria thing can ramp out of control when people start taking any number and turning into something from nothing (which happens a LOT).
But I could have that wrong. I'm no numberfag.
Well if you like gematria then maybe you’d like this too, long video 1hr 40 min but well worth your time. Maybe you’ve heard of Koinonia House. Pattern of 7’s in part 2 beg at 49:40 builds on Dr. Ivan Panin’s gospel research.
Rest In Peace Dr. Chuck Missler. I’m sure he heard “Well done good and faithful servant” on his entering in to Heaven 2 years ago.
