content: There are plenty of possible explanations for this, but my limited knowledge prevents me to see them all.  In the video the author tells us that those numbers represent those symbols and those symbols represent those words. If this is true then the rest might be true too. I don't know Hebrew, maybe someone could translate those words and also tell us if those letters have a numerical value. Even so, if it's true. It's very likely that when this alphabet was made, the ones in charge with assigning numerical values to the letters, did so while using this triangle as reference. There are also coincidences... Who knows?
