‘And the high priest stood up among them and asked Jesus saying, “Do you answer nothing? What is it that these witness against you?” But he held his peace and answered nothing.'
Like the Suffering Servant in Isaiah 53:7 Jesus did not defend Himself. ‘As a sheep that before her shearers is dumb, yes, He opened not his mouth.' He was not there to defend Himself but to suffer for the sins of others. But it exasperated the High Priest who probably had much experience in tripping up accused persons by their admissions when rebutting witnesses. But by His not answering the examination was reaching stalemate.
