Vol. 4 Eiruvin 1

Tractate Eiruvin, in its entirety, is an elaboration and conclusion of the subject matter discussed in tractate Shabbat, as it focuses on one aspect of the halakhot of Shabbat that was not comprehensively elucidated. Tractate Shabbat opened with a discussion of the prohibited labor of carrying out on Shabbat. Tractate Eiruvin analyzes the details of the rabbinic laws that apply to this act. This prohibited labor is unique in that it is not an inherently creative act; rather, it is merely the act of transferring an object from one domain to another.
