Eleven yeshiva stu- dents between the ages of 14 and 15 and another 16 of their younger counter- parts wowed an audience of rabbis, observant laypeople and thrilled parents with their memorization of the Talmud's Mesechta Bobo Metzia. The scene was Congregation Dovid Ben Nuchim in Oak Park, where the students gath- ered late last month to under- go a test of their knowledge. The annual event commemo- rates the yahrzeit of Rabbi Menachem Schneerson. The older students memo- rized the 240-page tractate in its entirety — and did not flinch as questions were fired at them from the audience.
