20
But the LORD hardened Pharaoh's heart, and he did not let the children of Israel go.
21
Then the LORD said to Moses, "Stretch out your hand toward heaven that there may be darkness over the land of Egypt, a darkness to be felt."
22
So Moses stretched out his hand toward heaven, and there was thick darkness in all the land of Egypt three days;
23
they did not see one another, nor did any rise from his place for three days; but all the people of Israel had light where they dwelt.
24
Then Pharaoh called Moses, and said, "Go, serve the LORD; your children also may go with you; only let your flocks and your herds remain behind."
