Isa. 53:7 clearly describes the scene on the day of Jesus’ crucifixion, where He is brought on trial before Pilate, Herod, and Caiaphas, the high priest. In all three cases, He is asked questions, but He decides not to speak. Even when false witness and testimony are brought against Him, He responds with silence.
Pilate was amazed at this, Caiaphas frustrated, and Herod disappointed. All of this is a fulfilment of the words spoken by Isaiah 700 years earlier,
“He was oppressed, and he was afflicted, yet he opened not his mouth; like a lamb that is led to the slaughter and like a sheep that before its shearers is silent, so he opened not his mouth.” Is. 53:7
Isaiah's prophecy points to this detail with great accuracy in the hope of showing the people of Israel the actions that the Messiah would take, so that they would recognise Him. Jesus chose to be handed over and delivered into the hands of these men. This choice was His submission to His Father, giving Himself as a free-will offering for our sins.
