An East wind.. now to the Natural Mind... one would have to think that there needs to be a 'west' embankment of some type to create the the wall of Water, the West embankment, the focal point of the East wind.. BUT the Word tells us there were WALLS ON BOTH SIDES.. mmmm that natural man , that doesnt work.. but WHAT ABOUT A STRONG east wind that takes the shape of a tunnel.. or horizontal vortex.. Always see the Weather geeks trying to explain how tornadoes form.. they talk of vertical winds and horizontal winds.. could God of created a 'tunnel ' of Wind.. strong enough to plow thru the Red Sea, thus creating walls on Both sides... OH INDEED.. now this could explain the walls on both sides.. a huge tunnel of wind.. wide in expanse .. outside this tunnel no wind at all.. wide enough to accomodate all the Israelites and their animals... mmm something to ponder on.. and to think this started at the END OF MOSES'S staff... very possible.. a supernatural God doing supernatural things!
