EXOD11 By their [Amram and Yoheved] listening to Miriam and then reuniting, the Torah is indicating to us that it is wrong not to have children, even in dire circumstances, even though the technical mitzvah was already fulfilled through Miriam and Aaron. Therefore, for those parents who do not want to bring babies into a cruel and immoral world, the Torah is indicating that this is not the Jewish way. There could be no more immoral world than was that of Egypt, and yet Miriam and her reasoning triumphed. Like the product of this union, Moses, that "unwanted" child, could indeed become the future leader of the people and holiest of prophets. In fact, as Pharaoh tried to limit the Jewish population by making conditions unbearable, the Torah tells us that God made sure that the Jewish population would continue to flourish nonetheless, even in these terrible physical and immoral conditions. This also reveals to us that God wanted the Jewish population to thrive. Despite all human attempts to limit Jews from being born, God continued to help the Jewish nation grow when the Jews themselves, like Amram and Yoheved, cooperated.
