Exodus 10:21-23

New Revised Standard Version Catholic Edition

The Ninth Plague: Darkness

²¹ Then the Lord said to Moses, “Stretch out your hand toward heaven so that there may be darkness over the land of Egypt, a darkness that can be felt.” ²² So Moses stretched out his hand toward heaven, and there was dense darkness in all the land of Egypt for three days. ²³ People could not see one another, and for three days they could not move from where they were; but all the Israelites had light where they lived.
