What was the theology of the exodus?

The book of Exodus is about the deliverance of the nation of Israel from bondage to Egypt. Pharaoh did not want to lose the great nation of slave workers. when approached by Moses with the request in Jehovah’s name to send the Israelites away that they might celebrate a festival to Him in the wilderness. What Pharaoh answered is recorded at Exodus 5:2. Pharaoh considered himself to be a god and did not recognize Jehovah’s authority. The issue here raised by Pharaoh’s attitude and actions brought up the question of Godship. It was now necessary for Jehovah God to exalt himself above the gods of Egypt, including Pharaoh, who was revered as a god. He did this by bringing Ten Plagues upon Egypt, which resulted in Israel’s release.
