'Silent' in the Bible

Then He said to them, “Is it lawful on the Sabbath to do what is good or to do what is evil, to save life or to kill?” But they were silent.

But they were silent, because on the way they had been arguing with one another about who was the greatest.

But He kept silent and did not answer anything. Again the high priest questioned Him, “Are You the Messiah, the Son of the Blessed One?”
