'Keep' in the Bible

The king replied to Haman, "Keep your money, and do with those people whatever you wish."

"Don't imagine that because you are part of the king's household you will be the one Jew who will escape. If you keep quiet at this time, liberation and protection for the Jews will appear from another source, while you and your father's household perish. It may very well be that you have achieved royal status for such a time as this!"
