'Law' in the Bible

Then the king flew into a rage. The king spoke to the wise men who understood the times, for it was the king's custom to consult all those who understood law and justice.

The king inquired, "According to law, what should be done to Queen Vashti because she did not obey the order of King Ahasuerus that was delivered by the eunuchs?"

"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."

"Go and gather all the Jewish people who are in Susa and fast for me. Don't eat or drink for three days, night or day. Both I and my young women will also fast in the same way, and then I'll go in to the king, even though it's against the law. And if I perish, I perish."

A copy of the document was to be issued as law in each and every province and published for all people, indicating that the Jewish people were to be ready to take vengeance on their enemies on that day.
