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 ^bfelt.

  5  And it came to pass after I saw these things, I saw the ^avapor of darkness, that it passed from off the face of the earth; and behold, I saw multitudes who had not fallen because of the great and terrible judgments of the Lord.

  11  For thus spake the prophet: The Lord God surely shall visit all the house of Israel at that day, some with his voice, because of their righteousness, unto their great joy and salvation, and others with the thunderings and the lightnings of his power, by tempest, by fire, and by smoke, and vapor of darkness, and by the opening of the earth, and by mountains which shall be carried up.
