Isaías 19
Ambrose of Milan · Comentário Patrístico (catena)
Isaías 19:1
Hear, for the flesh of the Lord was a shadow: Behold, the Lord sits upon a light cloud, and will come to Egypt. And David says: Protect me under the shadow of your wings. Therefore, he became a shadow emptied for us, whom the sun of iniquity had burned. We saw him in the shadow when faith first advanced. But now he illuminates the whole world: and yet we still see him through the shadow of his body, which is the Church, not yet face to face; for the eyes of the body are unable to receive the brightness of divinity. This shadow also protects the entire world every day. Therefore, the conclusion is beneficial; For God has concluded all in unbelief, that he may have mercy upon all. — Exposition on Psalm 118, 19.6
Isaías 19:11
And the Father says to him: Return to me, calling him from the earth to heaven, whom he had sent for our salvation. Therefore, raising up his only-begotten Son, he frustrated the plan of the slanderers. Hence, Isaiah also says: The futile plan of your spirit. And the one who had been accusing and directing arrows like a hunter, has disarmed everything: he has crushed the power of those who relied on their own strength and not on God. — On the Blessings of the Patriarchs, 11.49
Isaías 19:20
He said, I do not have a man; that is, because through a man is death, and through a man is the resurrection of the dead. He could not descend, he could not be saved, who did not believe that our Lord Jesus had taken flesh from the Virgin. But this one who was waiting for the mediator between God and men, the man Jesus Christ, expecting him of whom it was said: And the Lord will send a man to save them; he said: I do not have a man; and therefore he deserved to come to health, because he believed in the one who was coming. — On the Sacraments, 2.2.7
