Was bran used to make the shewbread in the temple?

No, actually they used mono atomic gold. When fired to the heat of the sun for so many seconds gold turns into a white powder. This came from Egypt. The powder was then baked into conical cakes. It heals the body at the DNA level and raises the consciousness to other dimensions. That's why the priests got so angry at David for eating the shew bread. The common man by their standards was not allowed to eat it. He then became king, didn't he? We have this powder today but only the very wealthy can attain it.
