The Torah teaches that mezuzos must be placed on the door into our houses (Deuteronomy 6:9). Does every room inside the house require a mezuzah as well? This question was asked of The Maharil (Rav Yaakov Moelin, 1365-1427) in an unusual way. The questioner felt that he wanted to show extra love for the mitzvah of mezuzah by placing a mezuzah on every door...

The Talmud (Menachos 33a) records testimony that the doorway through which Rabbi Yehuda Hanassi (Rebbe) entered his beis medrash did not have a mezuzah. The Talmud questions why it did not and refers to the beis medrash of Rav Huna as an example that such doorways should have a mezuzah.

When determining the kashrus of tefillin the most obvious issue is how often, if ever, should tefillin be opened for the parshios (writing) to be examined.

On which side of the door should the mezuzah be placed?

A mezuzah is placed on the right side of the doorway as one enters the room. We are commanded U’Ktavtam Al Mezuzot Beitecha, “you shall write it on the doorposts of the home” (Deut. 6:9). The Talmud (Menachos 34a) derives the word biascha which means “to come in” from the word beisecha and teache...

The first clear sign that a home belongs to a Jew is the mezuzah on the front door. While it is hard to imagine a case where the front door would not require a mezuzah, there are several halachik issues to consider.

Which door is the front door?

It’s not always obvious, and the answer to this question often has important ramifications for other doorways in...
