Midrasz do Rodzaju 45:16

When at last they recognized him, they sought to kill him. An angel descended and scattered them to the four corners of the room. At that moment, Judah screamed so loudly that all the walls of Egypt toppled, all the animals of Egypt gave birth prematurely, and Joseph and Pharaoh tumbled from their thrones. Their teeth fell out, and the heads of the powerful men standing at Joseph’s side were reversed and remained so until their deaths, as it is said: The lion roareth, and the fierce lion howleth—and the teeth of the young lions are broken (Job 4:10). Hence Scripture says: The voice thereof was heard in Pharaoh’s house (Gen. 45:16). The voice here refers to the voice of Judah, as it is said: Hear, Lord, the voice of Judah (Deut. 33:7).

“One is my faultless dove, one to her mother, pure to the one who bore her. Girls see her and laud her; queens and concubines, and praise her” (Song of Songs 6:9).
“One is my faultless dove”—“one,” this is Abraham, as it is stated: “Abraham was one” (Ezekiel 33:24). “One to her mother,” this is Isaac, who was an only child to his mother. “Pure [bara] to the one who bore her,” this is Jacob our patriarch, of whom it was clear [barur] to the one who bore him that he was entirely righteous. “Girls see her and laud her,” these are the tribes, as it is stated: “The news was heard in Pharaoh's palace, saying, "Joseph's brothers have come" (Genesis 45:16). Alternatively, “girls see her and laud her [vayashruha],” this is Leah, as it is stated: “In my happiness, as women will be happy for me [ishruni]” (Genesis 30:13).
“Queens and concubines, and praise her,” this is Joseph, as it is stated: “Pharaoh said to his servants: Can we find someone like this?” (Genesis 41:38). If we walk from one end of the world to the other we will not find someone like this, as it is stated: “After God has disclosed all this to you, [there is no one as insightful and wise as you]” (Genesis 41:39).
