To bring Vashti the queen before the king
 Not against her will, or by force; but they were sent to let her know it was the king's pleasure that she should come to him immediately: 
 with the crown royal;
 that is, upon her head, to make her look the more grand and majestic: 
 to show the people and the princes her beauty;
 for she was fair to look upon; which was not wisely done, neither was it comely nor safe.
