I gave my back to the smiters, and my cheeks to them that plucked out the beard: I hid not my face from shame and spitting.
All Commentaries on Isaiah 50:6 Go To Isaiah 50
Athanasius the Apostolic
And being by nature intangible, the Word yet said, “I gave my back to the stripes, and my cheeks to blows, and I hid not my face from shame and spitting.” For what the human body of the Word suffered, this the Word, dwelling in the body, ascribed to himself, in order that we might be enabled to be partakers of God the Word. Truly it is a mystery that it was he who suffered, and yet suffered not. He suffered, because his own body suffered, and he was in it, which thus suffered. He suffered not, because the Word, being by nature God, is impassible. And while he, the incorporeal, was in the passible body, the Body had in it the impassible Word, which was destroying the infirmities inherent in the body.
