To never a word - That is, not at all. He said nothing. This is, an emphatic way of saying that he answered nothing. There was no need of his replying. He was innocent, and they offered no proof of guilt. Besides, his appearance was full evidence in his favor. He was poor, unarmed, without powerful friends, and alone. His life had been public, and his sentiments were well known, and the charge had on the face of it the aspect of absurdity. It deserved, therefore, no answer.
Marvelled greatly - Wondered exceedingly, or was much surprised. He was probably more surprised that he bore this so meekly, and did not return railing for railing, than that he did not set up a defense. The latter was unnecessary - the former was unusual. The governor was not accustomed to see it, and was therefore greatly amazed.
It was at this time that Pilate, having heard them speak of Galilee Luke 23:5, asked if he was a Galilean. Having ascertained that he was, and being probably desirous of freeing himself from any further trouble in the affair, under pretence that he belonged to Herod's jurisdiction, he sent Jesus to Herod, who was then at Jerusalem attending the feast of the Passover, Luke 23:6-12. Herod, having examined him, and finding no cause of death in him, sent him back to Pilate. Pleased with the respect which had been shown him, Herod laid aside his enmity against Pilate, and they became friends. The cause of their friendship does not appear to be at all that they were united in opposing the claims of Jesus to be the Messiah, but the respect which Pilate had shown in sending Jesus to him.

Marveled greatly - Silence under calumny manifests the utmost magnanimity. The chief priests did not admire this because it confounded them; but Pilate, who had no interest to serve by it, was deeply affected. This very silence was predicted. Isaiah 53:7.

And he answered him to never a word,.... He made no reply to anyone thing which Pilate suggested to him, though it seems to have been in a kind and friendly way, and with a view to his good:
insomuch that the governor marvelled greatly; that a man, who at other times had such fluency of speech, and readiness of expression, who both for matter and words, and also weight and authority, spake as never man did: and who had so often silenced the Scribes and Pharisees, men of the greatest learning among the Jews, of which Pilate, doubtless, had knowledge, should say nothing in his own defence; and especially when the charges brought against him were of a capital nature, and touched his life, and yet were so easy to be refuted, and proved to be false ones: and what might increase his wonder, was, that he should take no notice of them, nor return an answer to them, considering by whom they were brought; not by the common people, but by the sanhedrim of the nation, and that before him the Roman governor, who had power to crucify or release him: and above all, he marvelled at the patience of Jesus, that he could hear such notorious falsities, and which so affected his character, and his life, and say nothing to them; and at the fortitude of his mind, at his being so regardless of his life, and fearless of death.
