New Revised Standard Version, Anglicised

The Ninth Plague: Darkness

²¹ Then the Lord said to Moses, ‘Stretch out your hand towards 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 towards 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.
