'Decree' in the Bible

According to the king's decree the drinking was not compulsory because the king instructed every steward in his house to serve each individual what he desired.

If it seems good to the king, let a royal decree go out from him and let it be written in the laws of Persia and Media, which cannot be repealed, that Vashti is never again to enter the presence of King Ahasuerus. Let the king give her royal position to another woman who is better than she.

Mordecai gave Hathach a copy of the written decree ordering the Jews' destruction that had been issued in Susa. Mordecai wanted him to show it to Esther, to explain it to her, and then to instruct her to go in to the king to seek his favor and plead with him for her people.
