'Law' in the Bible

And the drinking was in keeping with the law; no one was forced: for the king had given orders to all the chief servants of his house to do as was pleasing to every man.

And the king said to the wise men, who had knowledge of the times, (for this was the king's way with all who were expert in law and in the giving of decisions:

What is to be done by law to Vashti the queen, because she has not done what King Ahasuerus, by his servants, gave her orders to do?

Now every girl, when her turn came, had to go in to King Ahasuerus, after undergoing, for a space of twelve months, what was ordered by the law for the women (for this was the time necessary for making them clean, that is, six months with oil of myrrh and six months with sweet perfumes and such things as are needed for making women clean):

It is common knowledge among all the king's servants and the people of every part of the kingdom, that if anyone, man or woman, comes to the king in his inner room without being sent for, there is only one law for him, that he is to be put to death; only those to whom the king's rod of gold is stretched out may keep their lives: but I have not been sent for to come before the king these thirty days.

Go, get together all the Jews who are present in Shushan, and go without food for me, taking no food or drink night or day for three days: and I and my women will do the same; and so I will go in to the king, which is against the law: and if death is to be my fate, then let it come.

Giving the force of law to these days of Purim at their fixed times, as they had been ordered by Mordecai the Jew and Esther the queen, and in keeping with the rules they had made for themselves and their seed, in connection with their time of going without food and their cry for help.

The order given by Esther gave the force of law to the rules about the Purim; and it was recorded in the book.
