As we finish Masechet Beitzah, we learn various Rabbinic prohibitions that apply to the Festivals. We will also learn how to determine the Techum (permissible distance one may walk or carry an object) of various objects, including when that object is lent to another person with a different Techum and various public vs. private objects. The last Mishna deals with which animals may be slaughtered on the Festival and which are considered Muktza (not prepared for use on the Festival).
Congratulations on finishing Masechet Beitzah!!!
