Pharaoh wanted the Israelites to come back to Egypt. He didn’t have enough slaves left to do all the work the Israelites had done before they left.
So Pharaoh and his army chased after the Israelites. When the people saw the army coming, they were afraid. They couldn’t run away because they were at the edge of the Red Sea.
But God took care of His people. God told Moses to hold his hand out over the Red Sea. God sent a strong wind that blew and blew and made a path of dry land through the Red Sea. The people walked through the sea on dry ground!
The Egyptian army tried to follow them. When all the Israelites were safe on the other side, God told Moses to stretch his hand out over the sea again. The water went back into its place. Whoosh! The Egyptian army was covered up by the water.
All the Israelites trusted God because of the way He saved them from the Egyptians.
