Exodus 10:21
The Ninth Plague: Darkness
21 Then the Lord said to Moses, l“Stretch out your hand toward heaven, that there may be mdarkness over the land of Egypt, a darkness to be felt.”

30 They will growl over it on that day,
like the growling of the sea.
And if one looks to the land,
behold, rdarkness and distress;
and the light is darkened by its clouds.
