Rav Huna and Rabbi Aha in Rabbi Simon's name quoted "Dan, Joseph, and Benjamin," and taught that for the sake of Dan, Rachel was remembered; for the sake of Dan, Joseph and Benjamin were born (as a reward for Rachel's giving her rival Bilhah to Jacob, from whom was born Dan). Rabbi Johanan taught that God holds three keys that God does not entrust to any messenger: the key of rain, the key of childbirth, and the key of the revival of the dead. The Gemara cited to support the proposition that God holds the key of childbirth, as the verse says, "And God remembered Rachel, and God hearkened to her, and opened her womb." And the Gemara noted that Scripture uses the verb "bear" with regard to both childbirth, in , "she conceived, and bore a son," and rain, in , "the rain comes down and the snow from heaven, and returns not there, but waters the earth, and makes it bear and bud." Rabbi Akiva read the words "God . . . opened her womb" in to support the proposition that just as there is key to a house, there is a key to a woman's fertility. Rabbi Judah ben Pazi said in the name of the academy of Rabbi Yannai that Rachel showed that she was a prophetess when in she prophesied that she would bear another son, and by using the singular "son" she foretold that Jacob would have just one more son. Rabbi Samuel bar Nahmani, citing Rabbi Johanan, noted that 1 Chronicles reports that "the children of Issachar . . . had understanding." Rabbi Samuel bar Nahmani noted that reports that Jacob and Leah conceived Issachar after "Leah went out to meet him, and said: ‘You must come to me, for I have surely hired you.'" In contrast, Rabbi Samuel bar Nahmani noted that in , God told Moses, "Get you from each one of your tribes, wise men and understanding, and full of knowledge," but in , Moses reported, "So I took the heads of your tribes, wise men and full of knowledge," and Rabbi Samuel bar Nahmani thus deduced that Moses could not find men of "understanding" in his generation. Rabbi Samuel bar Nahmani concluded that a woman who solicits her husband to perform the marital obligation, as Leah did, will have children the like of whom did not exist even in
