Study Guide Chagigah 18 This week’s learning is sponsored by the Futornick Family, in honor of Michelle and Bill Futornick's anniversary. “B"H, we will begin our celebration on the plane ride back from Israel on March 1!”  Reish Lakish brings a different proof that one can make up the chagigah and re'iya sacrifices for Shavuot on the 6 days after the holiday. Rabbi Yochanan rejects this proof, although the Gemara points out that both agree that work is forbidden on Chol Hamoed. From where is that derived? Three different answers are brought to answer that question. The next Mishna sets up different categories of items that require purity and ranks them in terms of severity. The Mishna explains laws in which the ranking has relevance. The Mishna required washing one's hands for chulin and maaser sheni - however, another source contradicts this as it indicates there is no need for washing hands for those items. How is this contradiction resolved?
