קבלה אויף איוב 1:1

And you should know that Abraham and Nahor were brothers, and Isaac the son of Abraham and Utz the first born of Nahor were [cousins]. And Dinah, the daughter of Jacob, who was the son of Isaac, married Job, the grandson of Utz. And [about] that which is written, There was a man in the land of Utz (Job 1:1), you should know that Utz, the first born of Nahor, built a city close to the shore of Tiberias for himself, and he named the city after himself. And the translator [in the Targum] called this city, Armenia, and that is the first Constantinople. And Job was born in the land of Utz, which is Armenia, which is called Constantinople. Job was born in the second year that Dinah went down to Egypt. And when Job was eighteen years old, he was a prophet, a righteous man, and from the pious men of the nations of the world. And he went down to Egypt and married Dinah, his relative. And Dinah was also a prophetess, so she also knew that he was her relative. She also knew that he was born circumcised, and that is why he was called, unblemished. And that is why she was was willing to marry Job. Yet with all of this, if Jacob had been alive, she would not have married Job, even though he was a prophet, a pious man, and born circumcised. With all of this, he was still called uncircumcised, since he did not remove a drop of blood in order to convert. For Balaam was also born circumcised and [still] called uncircumcised.
