Read: Isaiah 53:7-9
He was oppressed and afflicted, yet he did not open his mouth; he was led like a lamb to the slaughter, and as a sheep before its shearers is silent, so he did not open his mouth. (Isaiah 53:7)
Scripture preserves carefully the sinlessness of Jesus himself. He was without sin, but he bore the sins of others. That is why he did it in silence. He had no interest in defending himself, so he never spoke in his own defense. It is a striking thing that in the gospel accounts of the trials of Jesus he never spoke up on his own behalf or tried to escape the penalty. This amazed both Pilate and Caiaphas. When our Lord stood before the High Priest, he was silent until the High Priest put him on oath to tell them who he was. When he stood before Pilate, he was silent until to remain silent was to deny his very Kingship. Then he spoke briefly, acknowledging who he was. When he was with the soldiers, they smote him and spat him and put the crown of thorns on his head, yet he said not a word. Peter says, When they hurled insults at him, he did not retaliate. (1 Peter 2:23). When he went before contemptuous, sneering Herod, he stood absolutely silent. He would not say one word to him. He was returned at last to Pilate because Herod could find nothing wrong with him.
