The Israelites were very happy to leave Egypt. They were no longer slaves, and they were going to the Promised Land! The Egyptians gave the Israelites whatever they asked for, even gold and silver and other valuable things. Some people from other nations believed in God and went along with the Israelites as they left Egypt.
A tall pillar of cloud went ahead of them during the day. It became a tall pillar of fire at night. God, who was in the pillar of cloud, was always with them and guided them as they traveled. All they had to do was follow him.
After a short time, Pharaoh and his people changed their minds. They wanted to make the Israelites their slaves again. So they chased after the Israelites. It was God who made them change their minds. He did this because he wanted everyone to know that he, Yahweh, is more powerful than Pharaoh and all the gods of the Egyptians.
When the Israelites saw the Egyptian army coming, they realized they were trapped between Pharaoh's army and the Red Sea. They were very afraid and cried out, "Why did we leave Egypt? We are going to die!"
Moses told the Israelites, "Stop being afraid! God will fight for you today and save you." Then God told Moses, "Tell the people to move toward the Red Sea."
God told Moses to raise his hand over the sea. Then God caused wind to push the water in the sea to the left and the right, so that there was a path through the sea.
So they followed the Israelites onto the path through the sea, but God caused the Egyptians to panic and caused their chariots to get stuck. They shouted, "Run away! God is fighting for the Israelites!"
The Israelites all arrived at the other side of the sea. Then God told Moses to stretch out his arm again over the water. When Moses did that, the water fell on the Egyptian army and returned to its normal place. The whole Egyptian army drowned.
The Israelites also rejoiced very much because God had saved them from dying and from being slaves. Now they were free to worship God and obey him. The Israelites sang many songs to celebrate their new freedom and to praise God because he saved them from the Egyptian army.
God commanded the Israelites to celebrate a festival every year in order to remember how God had defeated the Egyptians and freed them from being slaves. This festival was called the Passover. In it, they had to celebrate by killing a healthy lamb, roasting it, and eating it with bread made without yeast.
