21 And Moses stretched out his hand over the sea; and the Lord caused the sea to go back by a strong east wind all that night, and made the sea dry land, and the waters were divided.

22 And the children of Israel went into the midst of the sea upon the dry ground: and the waters were a wall unto them on their right hand, and on their left.

Here is the last wonder that the Egyptians would see, though not at all the last for the Israelites. Moses stretched out his hand, and a powerful wind blew from the east, the direction of Israel’s Promised Land, parting the sea. Notice that the parting of the Red Sea was not an instantaneous effect, though, but rather that it occurred over “all that night.” This was why the pillar of fire-on-one-side-and-cloud-on-the-other had been necessary. The Egyptians needed to be held in place for hours as the parting was accomplished.

Interestingly, the story becomes all the more incredulous by its the usage of natural phenomenon. When all the Egyptian firstborn were slain there was not any reference to a natural cause, and so we assume that an unseen heavenly figure from another plane of existence must have been responsible. But with the parting of the Red Sea, we are told it was effected by something as basic and familiar as the wind. The wind we are perfectly familiar with, and its behavior in this instance defies our typical experience.

Of course, in our everyday experience wind does move water, but enough to carve a channel through it? That might seem a stretch, though it does occur to me that we are never told the layout of the sea at that point. It seems like the most far-fetched thing would be if the wind was carving a channel through a large, convex shape, like an oval, but what if the sea in that area was bent and twisted, passing in front of the Israelites in a narrow channel? To me it seems like it might be possible that a strong enough wind could create a temporary bubble through that sort of narrow body, with the water pressed down on either side of the sustained air pressure.

Or perhaps there is some other physical phenomenon that can make such a thing possible, or perhaps there actually was a supernatural element to the parting. In either case, the way had been opened for the Israelites’ escape, though it would certainly require a step of faith and courage to take it!
