(JNS) American boxing legend Floyd Mayweather Jr. is donating $100,000 to buy 100 bulletproof vests for Israeli medical volunteers on the front lines, in his latest show of support for the Jewish state. The gift was announced at an annual Jerusalem concert for the United Hatzalah volunteer emergency-rescue service that raised funds for the purchase of 1,000 protective kits for its volunteers. About 3,000 people attended the sold-out event organized by the Jerusalem-based service at the city’s International Convention Center, which included performances by Israeli singers Ishay Ribo, Gad Elbaz and Shmuel Star. “Your presence shows that even in difficult times, we can find strength in unity,” said Eli Beer, United Hatzalah president and founder.
