'Law' in the Bible

The drinking was carried on in accordance with the law; no one was compelled [to drink], for the king had directed each official of his household to comply with each guest’s wishes.

Then the king spoke to the wise men who understood the times [asking for their advice]—for it was the custom of the king to speak before all those who were familiar with law and legal matters—

[He said,] “According to the law, what is to be done with Queen Vashti because she did not obey the command of King Ahasuerus which was conveyed by the eunuchs?”

“All the king’s servants and the people of the king’s provinces know that for any man or woman who comes to the king to the inner court without being summoned, he has but one law, that he is to be put to death, unless the king holds out to him the golden scepter so that he may live. And as for me, I have not been summoned to come to the king for these [last] thirty days.”

“Go, gather all the Jews that are present in Susa, and observe a fast for me; do not eat or drink for three days, night or day. I and my maids also will fast in the same way. Then I will go in to [see] the king [without being summoned], which is against the law; and if I perish, I perish.”
