The burden concerning Egypt. Behold, the LORD rides upon a swift cloud, and shall come into Egypt: and the idols of Egypt shall tremble at his presence, and the heart of Egypt shall melt in the midst of it.
All Commentaries on Isaiah 19:1 Go To Isaiah 19
John Chrysostom
AD 407
[At the Mount of Transfiguration] the Father uttered a voice out of the cloud. Why out of the cloud? Because this is how God appears. For a “cloud and darkness are around him.” “He sits on a light cloud,” and “He makes clouds his chariot.” “A cloud received him out of their sight.” “As the Son of Man coming in the clouds.”
His voice comes from a cloud so that they might believe that the voice proceeds from God.
