20. But the Lord made the king stubborn, and he did not let the Israelites go.
21. The Lord then said to Moses, “Raise your hand towards the sky, and a darkness thick enough to be felt will cover the land of Egypt.”
22. Moses raised his hand towards the sky, and there was total darkness throughout Egypt for three days.
23. The Egyptians could not see each other, and no one left his house during that time. But the Israelites had light where they were living.
24. The king called Moses and said, “You may go and worship the Lord; even your women and children may go with you. But your sheep, goats, and cattle must stay here.”
