This was 5 plus years ago, so I’m not sure what it took or where I found it. I do recall searching English language sites on “Persian” and “Zoroastrian” legends/mythology etc..
I do recall this man, repeatedly saying O BAM A. The proper or current spelling wasn’t the issue. The sound or pronunciation of the name was what he repeated, over and over again. I can honestly say that he expressed a fear of this man. He knew his history and what he expressed, was powerful enough for me to not only remember, but to seek out what his was talking about.
The Hebrew word “baraq” means lightning.
