In a telling account, the Rashbam wrote of a conversation with his eminent grandfather Rashi, regarding the interpretation of the Torah.
Rashi told him that if it were within his power, he would continuously revise his commentary “according to the textual insights that are revealed each day.”
These new insights unfold not only because studying the Torah is like contemplating a gem that has countless facets, but also because we, too, renew ourselves daily.
