21
And the Lord said to Moses, Stretch out thy hand to heaven, and let there be darkness over the land of Egypt—darkness that may be felt.
22
And Moses stretched out his hand to heaven, and there was darkness very black, even a storm over all the land of Egypt three days.
23
And for three days no man saw his brother, and no man rose up from his bed for three days: but all the children of Israel had light in all the places where they were.
24
And Pharao called Moses and Aaron, saying, Go, serve the Lord your God, only leave your sheep and your oxen, and let your store depart with you.
