Exodus 10:23
22. And Moses stretched forth his hand toward heaven; and there was a thick darkness in all the land of Egypt three days:23. They saw not one another, neither rose any from his place for three days: but all the children of Israel had light in their dwellings.24. And Pharaoh called unto Moses, and said, Go ye, serve the LORD; only let your flocks and your herds be stayed: let your little ones also go with you.
