Mark 15:3

He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth.

And from thenceforth Pilate sought to release him: but the Jews cried out, saying, If thou let this man go, thou art not Caesar’s friend: whosoever maketh himself a king speaketh against Caesar.

And when he was accused of the chief priests and elders, he answered nothing.

But Jesus yet answered nothing; so that Pilate marvelled.
