This week we will learn about the 4th species, the Etrog and what makes it valid or invalid. We will learn about someone who is on a journey over Sukkot and when they are required to find a Lulav to shake. We will learn the laws pertaining to the recitation of the Hallel. And since we are learning about the Etrog, many laws of the Shemita year come up in this week’s daf.
