Avot 6:11 and Horayos 1:1

R' Zecharia Resnik has been living in Israel since 2007. He spends his days learning in a local Halacha kollel in Yerushalayim, where he lives with his wife and five children. At times when Zecharia isn't in kollel [or preparing the Daf!], he is involved in speaking engagements and numerous chesed projects in and around the neighborhood.
