God strikes down all the firstborn sons of Egypt including Pharaoh's son in the 10th plague, and Pharaoh recognizes that this is God's punishment. Finally by God�s grace, after 430 years in Egypt, Israel leaves and begins the exodus into freedom under the one true God. God sets Israel apart by instituting the Passover Feast and the Feast of Unleavened Bread, marking a new era for Israel and foreshadowing the new spiritual Israel in Christ. Moses said to the people, "Fear not, stand firm, and see the salvation of the Lord�" -- Exodus 14:13
