תּלמוד אויף מלאכי 2:16

So we have established that Gentiles have no preliminary marriage. Do they have divorce? Rebbi Jehudah ben Pazi and Rebbi Ḥanin in the name of the great Rebbi Ḥuna of Sepphoris: Either they have no divorce, or either of them may divorce the other. Rebbi Joḥanan from Sepphoris, Rebbi Aḥa, Rebbi Ḥinena, in the name of Rebbi Samuel bar Naḥman: “For the divorcer is hateful, says the Eternal, Israel’s God.⁵⁷Mal. 2:16, speaking of the person divorcing his first wife without necessity.” In Israel I gave divorce, I did not give divorce among the nations of the world. Rebbi Ḥananiah in the name of Rebbi Phineas: In the entire paragraph it is written “the Eternal, Sabaot”; only here it is written “Israel’s God.” To teach you that the Holy One, praise to Him, did lend his name only to Jewish divorce.
