Exodus 10:21-29

21The Lord said to Moses, “Extend your hand toward heaven so that there may be darkness over the land of Egypt, a darkness so thick it can be felt.”

22So Moses extended his hand toward heaven, and there was absolute darkness throughout the land of Egypt for three days.

23No one could see another person, and no one could rise from his place for three days. But the Israelites had light in the places where they lived.

24Then Pharaoh summoned Moses and said, “Go, serve the Lord – only your flocks and herds will be detained. Even your families may go with you.”

25But Moses said, “Will you also provide us with sacrifices and burnt offerings that we may present them to the Lord our God?

26Our livestock must also go with us! Not a hoof is to be left behind! For we must take these animals to serve the Lord our God. Until we arrive there, we do not know what we must use to serve the Lord.”

27But the Lord hardened Pharaoh’s heart, and he was not willing to release them.

28Pharaoh said to him, “Go from me! Watch out for yourself! Do not appear before me again, for when you see my face you will die!”

29Moses said, “As you wish! I will not see your face again.”
