DEUT526 Are grandparents responsible for teaching their grandchildren? … “And you shall teach your children” (Deuteronomy 11:19), from that I only know that I must teach my children; how do I know that I must also teach my grandchildren? Because the Torah says, “and make them known to your children and to your children's children” (Deuteronomy 4:9). Babylonian Talmud, Kiddushin 30a. In our own day, this implies that grandparents have a duty to help their children provide a Jewish education for their grandchildren. That includes providing a Jewish model for their grandchildren, especially if they are the product of an interfaith marriage. For grandparents who have greater financial resources than their adult children as well as fewer economic responsibilities, this duty also includes paying the tuition (or part of it) for their grandchildren's Jewish day school or religious school education, camp, or youth group. Grandparents may feel good about themselves in doing this, but not too good: after all, they are simply fulfilling their Jewish legal duty!
