And the glory of the LORD shall be revealed, and all flesh shall see it together: for the mouth of the LORD has spoken it.
All Commentaries on Isaiah 40:5 Go To Isaiah 40
Ambrose of Milan
AD 397
He [Christ] was a reproach but at the same time also the majesty of the Lord, as it is written, “And the glory of the Lord shall be revealed, and all flesh together shall see the salvation of God.” What had he lost if he had nothing less? He had neither comeliness nor beauty, but he had not ceased to be the power of God. He appeared a man, but the divine majesty and glory of the Father shone on earth.
