And they covered all the face of the earth, so that the land was dark therewith. And they ate all the herbs of the land and all the fruits of the trees which the hail had left: so that there was no green thing left in the trees and herbs of the field through all the land of Egypt.

And Moses stretched forth his hand unto heaven, and there was a dark mist upon all the land of Egypt three days long,

and went between the host of the Egyptians and the host of Israel. It was a dark cloud, and gave light by night: so that all the night long the one could not come at the other.
