Behold, I have engraved you upon the palms of my hands; your walls are continually before me.
Read Chapter 49
Ambrose of Milan
Let us flee these evils and elevate our soul to the image and likeness of God. The flight from evils is the likeness of God, and the image of God is gained through the virtues. And so, like a painter, he has painted us with the colors of the virtues. “See, I have painted your walls, Jerusalem.” Let us not wipe away with the brush of neglect the props of the painted walls of our soul. - "Death as a Good 5.17"
He bore our sins in his body on the cross, and as he lay there, we were saved, and his sufferings became for us like a safe place and a protecting wall. He suffered outside the city so that he could sanctify the people with his own blood. Therefore … the suffering of Christ and his precious cross and the nailing of his hands became safety and an impregnable wall without any breach for those who believe in him. Thus he says, “I have painted your walls on my hands.” … And if one wants to understand this in another way, I think it makes sense to understand it that all who believe in Christ are in the hands of the Father.… The walls of the spiritual Zion are the holy prophets and apostles as ones written on his hands, set there by God and having the knowledge of him that does not fade. For their names were written in the heavens and included in the book of life. - "Commentary on Isaiah 126.96.36.199–17"
