'Knows' in the Bible

"Every servant of the king and every person in the king's provinces knows that for any man or woman who goes to the king in the inner court without being summoned there is only one law that he be put to death unless the king holds out the golden scepter to him. Only then he will live. For these last 30 days I've not been summoned to come to the king."

If you keep silent at this time, liberation and deliverance will come to the Jewish people from another place, but you and your father’s house will be destroyed. Who knows, perhaps you have come to your royal position for such a time as this.”
