From Egypt, God sent the Israelites south, to avoid possible conflicts with the Philistines. They were on the edge of the Red Sea when the Egyptian army ran them down. The Israelites were afraid because they were trapped against the sea and the Egyptians had a well trained army with chariots and horses. Moses told the Isralites to "be still" for "The Lord will fight for you." Is there a single army that can stand against God? No. Does God need our help to defeat his enemies. No.
The angel of the Lord and the pillar of cloud stood between the two groups. The cloud lit up the night. Neither camp approached the other. God told Moses to lift his staff and hold it over the sea. While Moses did this, God sent an East wind to blow against the sea. Soon there was dry land for the Israelites to cross over upon, and walls of water on both sides. The Israelites crossed over.
