It's impossible to know what Jesus was thinking as he was being brutally mocked. Perhaps Isaiah was given a glimpse into the Lord's mindset. Perhaps the Master thought of this passage as the villainous blows landed:
'the Lord God will help me, therefore shall I not be confounded. Therefore have I set my face like a flint, and I know that I shall not be ashamed.
And the Lord is near, and he justifieth me. Who will contend with me (at the last day)? Let us stand together (for now I stand alone). Who is mine adversary? Let him come near me, and I will smite him with the strength of my mouth (in the day of vengeance, for vengeance is mine, saith the Lord)
For the Lord God will help me. And all they [who condemn me this day] shall wax old as a garment, and the moth shall eat them up.'
