I just heard this from my husband. Rav Raphael Shmuel Berenbaum, zt'l, had passed away today. The Jewish world had lost one of the greatest sages of our time. My husband said he had never seen so many grown men cry.
I never know what to say during these times, so I won't say anything... My heart goes out to his family, friends, students and anyone mourning him. :'(
Update: The levayah will be held at Mirrer Yeshiva starting 8.45 am until about 11 am, and then the body will be flown to Eretz Yisrael for burial.
