Rujukan Talmud untuk Kejadian 18:13: Jerusalem Talmud Peah & Yevamot

Rebbi Ḥanina said: Come and see, how hard is even a hint of calumny that the verses spoke untruth in order to make peace between Abraham and Sarah. (Gen. 18:12) “Sarah laughed to herself, saying: After having wilted I became dainty¹⁶⁰Her wrinkles had disappeared and her period restarted., but my master is old.” To Abraham He does not say so, but rather (Gen. 18:13): “Why now did Sarah laugh, saying how can I give birth, being old?” It is not written “my master is old” but “I am old”. Rabban Simeon ben Gamliel said¹⁶¹The formulation in Bereshit rabba 100(9) is easier to understand: We have stated: Rabban Simeon ben Gamliel said, peace is great because even the tribes spoke untruth to obtain peace between themselves and Joseph.: Come and see, how hard is even a hint of calumny that the verses spoke untruth in order to make peace between Joseph and his brothers. That is what is written (Gen.50:16–17): “They empowered [a messenger] to Joseph to say: Your father commanded before his death, saying: So you shall say to Joseph, please forgive etc.” We do not find that he (Jacob) commanded anything.

The school of R. Yishmael taught: peace is so important that even God altered what was said for its sake! For at first, [Sarah says] “My husband is old” and afterwards, [when God repeats her words to Abraham] it says “I am old.” (Gn 18:12)
