reveal his failing, and Joseph swore. Later, in , when Joseph related to Pharaoh that Jacob had made Joseph swear to bury him in the Land of Israel, Pharaoh asked Joseph to seek to be released from the oath. But Joseph replied that in that case, he would also ask to be released from his oath to Pharaoh concerning Pharaoh's ignorance of languages. As a consequence, even though it was displeasing to Pharaoh, Pharaoh told Joseph in , "Go up and bury your father, as he made you swear." Reading , "He placed food in the cities; the food that came from a city's surrounding fields he placed in its midst", Rabbi Judah taught that Joseph stored the crops of Tiberias in Tiberias, and the crops of Sepphoris in Sepphoris, so that every region preserved its own produce. Rabbi Judah thus argued that Joseph increased efficiency by decentralizing food distribution. The Rabbis observed that if all the citizens of Tiberias consumed the produce grown in Tiberias, and all the citizens of Sepphoris consumed the produce grown in Sepphoris, then they would not get a handful each. The Rabbis concluded that a blessing rested on the stored produce, for there was enough for all. Resh Lakish deduced from the words, "And to Joseph were born two sons before the year of famine came", in that Joseph did not have marital relations during the famine, and generalized that no man should. The Gemara qualified the injunction, however, teaching that childless people may have marital relations in years of famine. Similarly, reading , "And to Joseph were born two sons", Rabbi Muna and Rav Huna taught that this occurred before the famine came. A Midrash applied the words of , "the king's word has power" (, shilton) to Joseph's story. The Midrash taught that God rewarded Joseph for resisting Potiphar's wife by making him ruler (, hashalit) over the land of Egypt (as reported in ). "The king's word" of were manifest when, as reports, "Pharaoh spoke to Joseph: In my dream ..." And the word "power" (, shilton) of corresponds to the report of , "And Joseph was the governor [, hashalit] over the land." The words of , "And who may say to him: 'What are you doing? are thus reflected in Pharaoh's words of , "Go to Joseph; what he says to you, do." The Midrash taught that Joseph received
