Kiddushin, Daf Lammed Daled, Part 1
Introduction
This week s daf begins by listing some positive commandments that are time-bound and thus women are exempt, and some that are not time-bound and thus women are obligated.
כל מצות עשה שהזמן גרמא וכו’:
ת"ר איזוהי מצות עשה שהזמן גרמא סוכה ולולב שופר וציצית
ותפילין
All positive commandments that have a set time etc.
Our Rabbis taught: What are positive commandments that have a set time? Sukkah, lulav, shofar, tzitzit, and tefillin.
Sukkah and lulav can be performed only on Sukkot, and the shofar only on Rosh Hashanah.
Tzitzit is not worn at night, and tefillin are not worn on Shabbat or holidays. Thus these too have a set time.
ואיזוהי מצות עשה שלא הזמן גרמא מזוזה מעקה אבידה ושילוח הקן
And what are positive commandments that do not have a set time?
Mezuzah, guard rail, [returning] lost property, and sending away the mother bird.
Most of these are self-explanatory. The guard rail refers to the commandment to put a railing around one s roof so that no one falls off.
