I was just reviewing the story in Exodus of the battle of wills between Yahweh, Moses, Aaron, and the Pharaoh. The climax of the story is in Exodus 14, when Moses parts the Red Sea to effect the escape of the Israelites from Pharaoh's persuing army (Ex 14:7, six hundred chariots - all the chariots of Egypt), then releases the Sea to swallow up the army.
However, was Pharaoh's army in any condition to persue the Israelites out of Egypt to the shores of the Red Sea? The 10 plagues Yahweh, Moses, and Aaron, brought on the Egyptians (but not on the Israelites), left them for days without water, food, and harassed with lice and and painful boils.
In addition, all Egyptian livestock, including cattle, sheep, assess, and horses were killed (Exodus 9:3-6); so what did Pharaoh's army - such as it was after the plagues - use to pull the 600 chariots to persue the Israelites to the Red Sea?
