DEUT147 Marriage provides the venue for having children but is also, in the Jewish view, the context in which children are educated. Parents have a duty to educate their children in Judaism, including its moral component. (Deuteronomy 6:7, 20-25, 11:19. This was already one of Abraham's duties (Genesis 18:19)). Parents may use schools to help them fulfill that duty, but they must periodically check to make sure that their children are in fact learning what they should, because ultimately the duty to educate children remains theirs. Moreover, much of the Jewish tradition can be taught only at home, for this is a tradition that is not restricted to the synagogue or school: It tends to influence virtually every detail of life.
