A Holy Lineage
Reb Aharon was the oldest son of the third Rebbe of Belz, Reb Yisachar Dov. From his youth, Reb Aharon had the utmost respect and reverence for his father and for all his ancestors. He meticulously followed all their customs, which he regarded as sacred as the Torah itself.
In turn, his father and grandfather saw greatness in the young man’s demeanor, recognizing that a soul such as Reb Aharon’s is a gift from Heaven unique in his generation.
