Moses and the ten plagues 

Moses and the ten plagues (Genesis 7-13) - But I will make Pharaoh’s heart stubborn so I can multiply my miraculous signs and wonders in the land of Egypt. Even then Pharaoh will refuse to listen to you. So I will bring down my fist on Egypt. Then I will rescue my forces-my people, the Israelites-from the land of Egypt with great acts of judgment. When I raise my powerful hand and bring out the Israelites, the Egyptians will know that I am the Lord.”
