'Memorial' in the Bible

and the giving of drink in vessels of gold, and the vessels are divers vessels, and the royal wine is abundant, as a memorial of the king.

and the king maketh a great banquet to all his heads and his servants -- the banquet of Esther -- and a release to the provinces hath made, and giveth gifts as a memorial of the king.

and these days are remembered and kept in every generation and generation, family and family, province and province, and city and city, and these days of Purim do not pass away from the midst of the Jews, and their memorial is not ended from their seed.
