Exodus 10:21-23

The Plague of Locusts

²¹Then the Lord said to Moses, “Reach out with your hand toward the sky, so that there may be darkness over the land of Egypt, even a darkness which may be felt.” ²²So Moses reached out with his hand toward the sky, and there was thick darkness in all the land of Egypt for three days. ²³They did not see one another, nor did anyone rise from his place for three days, but all the sons of Israel had light in their dwellings.
