Exodus 10:21-23 Holman Christian Standard Bible (HCSB)
The Ninth Plague: Darkness
21 Then the Lord said to Moses, “Stretch out your hand toward heaven, and there will 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 thick darkness throughout the land of Egypt for three days. 23 One person could not see another, and for three days they did not move from where they were. Yet all the Israelites had light where they lived.
