God - through Boaz - is the provider of food and children. Naomi's plan to seduce Boaz is beneficial for Ruth and for herself. The immodest plan that Naomi develops is based on the biblical precedents of the daughters of Lot with Lot - the progenitors of Ruth - and Tamar with Yehuda - the progenitors of Boaz.
