'Silent' in the Bible

Then He asked them, "Are we allowed to do good on the Sabbath, or to do evil? to save a life, or to destroy one?" They remained silent.

Then He went up to them on board the boat, and the wind lulled; and they were beside themselves with silent amazement.

But they remained silent; for on the way they had debated with one another who was the chief of them.

But He remained silent, and gave no reply. A second time the High Priest questioned Him. "Are you the Christ, the Son of the Blessed One?" he said.
