Midrash su Genesi 41:6

And Pharaoh said unto Joseph: “I have dreamed a dream (ibid.). As he was about to relate the dream to him, he decided to test Joseph by altering the dream slightly. He said: “Seven kine went up out of the Nile, fat and well-formed,” whereupon Joseph replied: “That is not so, you saw fat and healthy kine.” “And there were,” he said to him, “seven lean and ill-favored kine.” And Joseph replied: “You did not see this but rather ugly-appearing and thin-fleshed kine.” “And there were seven full and good ears of corn,” he continued. Whereupon Joseph answered: “That too is not so, you saw fat and good ones.” “There were seven shrunken ears of corn,” he added. And Joseph responded: “That is not so, you beheld seven ears of corn, withered thin and blistered by the east wind.” Pharaoh began to wonder about this. He said to him: “You must have been behind me when I had my dream,” as it is said: For inasmuch as God hath shown thee all this, there is none so discreet and wise as thou (ibid. v. 39).

Why did Pharaoh and his servants approach him, saying: Get you? The time Pharaoh told him: Get thee from me, see my face no more (ibid. 10:29), he (Moses) insisted: But we shall not leave until all these servants shall come down unto me (ibid. 11:9), to escort us from this place. This verse indicates that Moses paid homage to royalty, since he did not say to him: “You and all your servants.” In fact, the Holy One, blessed be He, had previously charged Moses and Aaron to be respectful to royalty, as it is said: And the Lord spoke unto Moses and Aaron, and gave them a charge unto the children of Israel, and unto Pharaoh king of Egypt (ibid. 6:13). Joseph was respectful to royalty when he said: It is not in me; God will give Pharaoh an answer of peace (Gen. 41:6). Jacob was respectful to royalty; and Israel strengthened himself, and sat upon the bed (ibid. 49:2). Elijah paid homage to royalty, as is said: And the hand of the Lord was on Elijah (I Kings 18:46). Hananiah, Mishael, and Azariah also were respectful to royalty, and so was Daniel.
