²¹ And the Lord said unto Moses, Stretch out thine hand toward heaven, that there may be darkness over the land of Egypt, even darkness which may be felt.

²² And Moses stretched forth his hand toward heaven; and there was a thick darkness in all the land of Egypt three days:

²³ They saw not one another, neither rose any from his place for three days: but all the children of Israel had light in their dwellings.

⁷ He spake unto them in the cloudy pillar: they kept his testimonies, and the ordinance that he gave them.
