מדרש אויף מלכים א 8:50

[3] Another interpretation:"And El Shaddai did not need to say 'grant you mercy' but rather 'grant you mercy before the king,' or 'before the ruler,' just as it is written, 'and Joseph was the ruler, etc.'" (Genesis 42:6) Why does it say "before the man"? It could have just said to give you mercy before the king, or before the ruler, as it is written "and Joseph was the ruler, etc." (Genesis 42:6). And why did his mother call him by his name Joseph, as it is written "And she called his name Joseph" (Genesis 30:24), while Pharaoh called him Zaphenath-paneah ["treasury of the glorious rest"] (Genesis 41:45) and the Egyptians called him Avrech [father in wisdom.] (Genesis 41:43)? Jacob omitted all of these names and only said "And El Shaddai, etc." before the man. Why, when his father sent him to his brothers, did the angel who was assigned by God to watch over him find him wandering and ask him what he was looking for? As it is written "And a man found him, and behold he was wandering in the field" (Genesis 37:15), and he said to him "What are you looking for?" and he answered "I am looking for my brothers." Once he arrived there, they threw him into a pit, then took off his coat, and then sold him four times, as it is written "Thus says the Lord: For three transgressions of Israel, and for four, I will not turn away" (Amos 2:6). And when the tribes went down to Egypt, as soon as he saw them, he had compassion on them." As it is written, "And Joseph recognized them" (Genesis 42:8). "And he turned himself away from them and wept" (Genesis 42:24). Immediately, the angel descended and appeared to Joseph in the form of a man, and he said to him, "Why do you have mercy on these people? Don't you know how much they have troubled you? They threw you into a pit and sold you four times. He began to accuse them and said to Joseph, "Immediately he revealed himself to them" (Genesis 45:1). He said to them, "Don't you know that I am a magician? I take the cup, smell it, and make myself a magician. He said to them, "I know that you are spies, but if you are honest, then you are finished." (Genesis 42:19). When they came to Jacob and said to him, "What do you think the king of Egypt said to us? He is not merciful to us." Only one person knows where he sent us from, and he stands and accuses us before him, as it is written, "The man said, 'Your servant, our lord, has asked us about our family'" (Genesis 43:7). For the man said, "You are spies" (Genesis 42:14). He said to them, "There is a man who accuses you, so be kind to him, as it is written, 'And Almighty God will give you mercy before the man' (Genesis 43:14), and not only before this man, but before all nations, as it is written, 'give them compassion before those who carried them captive.' (I Kings 8:50)"
