전도서 4:15의 Quotation

The inability to identify with posterity is a defect which is characteristic of living only under the sun. The alienation from ancestors and from succeeding generations results from the narrow focus of getting and spending, for living only under the sun. The first mitzvah in the Torah is to be fruitful and multiply, that is to dedicate our efforts for succeeding generations. Like all of the mitzvot, having and rearing children is a pathway for moving beyond what is under the sun.
