Exodus 10:22-24

New Century Version

²² Moses raised his hand toward the sky, and total darkness was everywhere in Egypt for three days. ²³ No one could see anyone else, and no one could go anywhere for three days. But the Israelites had light where they lived.

²⁴ Again the king of Egypt called for Moses. He said, “All of you may go and worship the Lord. You may take your women and children with you, but you must leave your flocks and herds here.”
