'Laws' in the Bible

“If it meets the king’s approval, he should personally issue a royal decree. Let it be recorded in the laws of Persia and Media, so that it cannot be revoked: Vashti is not to enter King Ahasuerus’s presence, and her royal position is to be given to another woman who is more worthy than she.

Then Haman informed King Ahasuerus, “There is one ethnic group, scattered throughout the peoples in every province of your kingdom, yet living in isolation. Their laws are different from everyone else’s and they do not obey the king’s laws. It is not in the king’s best interest to tolerate them.
