Rabbi Moshe Isserles, known as the Rema and author of the glosses on Shulchan Aruch, wrote his first book, Mechir Hayayin, while fleeing from the plague that swept through his home town of Krakow.
In this class we look at some details of the life and ideas of the Rema, and learn a few verses of his commentary on Megillat Esther.
