A group of Jewish students studying in Jerusalem found a lost backpack containing expensive jewelry, watches, and cash at Newark Airport. The bag, valued at over $100,000, belonged to a man working in New York City's Diamond District. The students contacted a Brooklyn public safety group, Shmira, who helped return the bag to its rightful owner. The owner was ecstatic and offered a reward, which the students declined, showcasing their honesty and integrity. The heartwarming story highlights the students' commitment to doing good deeds, or mitzvahs, in their daily lives.
