'Silent' in the Bible

but if thou keep entirely silent at this time, respite and deliverance remaineth to the Jews from another place, and thou and the house of thy fathers are destroyed; and who knoweth whether for a time like this thou hast come to the kingdom?'

for we have been sold, I and my people, to cut off, to slay, and to destroy; and if for men-servants and for maid-servants we had been sold I had kept silent -- but the adversity is not equal to the loss of the king.'
