Pastor Corey dramatizes the story of the Passover. (Please note: the recording has a lot of problems for which we apologize. In the first few minutes, there are many gaps in the recording, and then the later parts have some echoing which gives some difficulty.)
Exodus 7:1-7, 12:12-13 (ESV)
And the Lord said to Moses, “See, I have made you like God to Pharaoh, and your brother Aaron shall be your prophet.You shall speak all that I command you, and your brother Aaron shall tell Pharaoh to let the people of Israel go out of his land. But I will harden Pharaoh's heart, and though I multiply my signs and wonders in the land of Egypt, Pharaoh will not listen to you. Then I will lay my hand on Egypt and bring my hosts, my people the children of Israel, out of the land of Egypt by great acts of judgment. The Egyptians shall know that I am the Lord, when I stretch out my hand against Egypt and bring out the people of Israel from among them.” Moses and Aaron did so; they did just as the Lord commanded them. Now Moses was eighty years old, and Aaron eighty-three years old, when they spoke to Pharaoh. ....
For I will pass through the land of Egypt that night, and I will strike all the firstborn in the land of Egypt, both man and beast; and on all the gods of Egypt I will execute judgments: I am the Lord. The blood shall be a sign for you, on the houses where you are. And when I see the blood, I will pass over you, and no plague will befall you to destroy you, when I strike the land of Egypt.
