Esther 4:11
"All the royal officials and the people of the king's provinces know that one law applies to every man or woman who approaches the king in the inner court without being summoned--that he be put to death. Only if the king extends the gold scepter may that person live. But I have not been summoned to appear before the king for the past thirty days."

Esther 4:13
