Exodus 10:21-22 AMP

Then the LORD said to Moses, “Stretch out your hand toward the sky, so that darkness may come over the land of Egypt, a darkness which [is so awful that it] may be felt.” So Moses stretched out his hand toward the sky, and for three days a thick darkness was all over the land of Egypt [no sun, no moon, no stars].
