You take a snake, dislocate it’s head, and tetany is induced. You throw your snake down with a flick of the wrist that relocates the snake’s head and it is seemingly reanimated. I don’t know if Moses’ staff was one such snake. He was kicking around the outback for quite a while, and may have learned the trick, like swamp folk learn to hypnotize alligators by flipping them on their back and stroking their stomachs; or farm folk learn to hypnotize chickens by putting something beak-close.
And Moses was educated as a prince of Egypt and knew where all the bodies were buried. I would hypothetically guess that others who would have tried to control or impress Pharaoh would have, previous to Moses, been dismissed by the snake trick; and I think Moses may indeed have had a mega-snake staff at the ready. Or God miraculously changed Moses’ staff into a snake-eating mega-snake.
The upcoming prophesied miracle will be all nations going up to Jerusalem to celebrate Sukkoth, the Feast of Tabernacles re-enacting camping out after leaving Egyptian slavery, honoring the heritage of FREEEEEEEEEEDOM!
