창세기 17:30의 Tosefta

Similar to this [it says]: “Sarai, your wife, will not be called Sarai anymore, because her [new] name is Sarah.” (Genesis 17:15) In the beginning, she was a princess over her nation, [but] now she became a princess for all of the nations of the world, as it is said: “…because her [new] name is Sarah.” Similar to this [it says]: “And your name will not be called anymore Avram, but rather your name will be Avraham…” (Genesis 17:5) In the beginning, you were a father to Aram and now you will be a father to all people of the world, as it is said: “… because I have made you a father of a multitude of nations”.(ibid)

Even though [the Tanach] goes back and calls Avraham [(Genesis 17:5)], Avram [again], [(Nehemiah 9:7) and (I Chronicles 1:27)] it is in his praise and not in his shame. To Yehoshua [(Numbers 13:16)], Hoshea [again], [(Deuteronomy 32:44)] it is in his praise and not in his shame. He is [the same] Avram before [God] spoke to him, he is [the same] Avram after [God] spoke to him. He is [the same] Hoshea before he became great , he is [the same] Hoshea after he became great. Moshe, Moshe [(Exodus 2:3)]; Avraham, Avraham [Genesis 22:11)]; Yakov, Yakov [(Genesis 46:2)]; Shmuel, Shmuel [(I Samuel 3:10)]; [all of these double expressions] are expressions of love and encouragement. They are [the same people] before [God] spoke to them and they are [the same people] after [God] spoke to them. They are [the same people] before they became great, they are [the same people] after they became great.
