This week’s article discusses the halachos of Parashas Zachor, which is read this week in advance of Purim. Is the reading of Zachor a Torah mitzvah, or a rabbinic enactment? Does the mitzvah require a kosher Sefer Torah, and a reading among a quorum of men? Are women obligated in the mitzvah? These questions, and more, are discussed this week.This week’s Q & A addresses the question of inviting others to a bris (and responding to an invitation).
