(4) Abram went forth as the LORD had commanded him, and Lot went with him. Abram was seventy-five years old when he left Haran. (5) Abram took his wife Sarai and his brother’s son Lot, and all the wealth that they had amassed, and the persons that they had acquired in Haran; and they set out for the land of Canaan. When they arrived in the land of Canaan,
(1) When Abram was ninety-nine years old, God appeared to Abram and said to him, “I am El Shaddai. Walk in My ways and be blameless. (2) I will establish My covenant between Me and you, and I will make you exceedingly numerous.”
(5) And you shall no longer be called Abram, but your name shall be Abraham, for I make you the father of a multitude of nations. (6) I will make you exceedingly fertile, and make nations of you; and kings shall come forth from you. (7) I will maintain My covenant between Me and you, and your offspring to come, as an everlasting covenant throughout the ages, to be God to you and to your offspring to come. (8) I assign the land you sojourn in to you and your offspring to come, all the land of Canaan, as an everlasting holding. I will be their God.” (9) God further said to Abraham, “As for you, you and your offspring to come throughout the ages shall keep My covenant. (10) Such shall be the covenant between Me and you and your offspring to follow which you shall keep: every male among you shall be circumcised. (11) You shall circumcise the flesh of your foreskin, and that shall be the sign of the covenant between Me and you.
(17) Abraham threw himself on his face and laughed, as he said to himself, “Can a child be born to a man a hundred years old, or can Sarah bear a child at ninety?”
ועמדו עליו שבע נביאות מאן נינהו שרה מרים דבורה חנה אביגיל חולדה ואסתר שרה דכתיב (בראשית יא, כט) אבי מלכה ואבי יסכה ואמר ר' יצחק יסכה זו שרה ולמה נקרא שמה יסכה שסכתה ברוח הקדש שנאמר (בראשית כא, יב) כל אשר תאמר אליך שרה שמע בקולה ד"א יסכה שהכל סוכין ביופיה
The Gemara asks with regard to the prophetesses recorded in the baraita: Who were the seven prophetesses? The Gemara answers: Sarah, Miriam, Deborah, Hannah, Abigail, Huldah, and Esther. The Gemara offers textual support: Sarah, as it is written: “Haran, the father of Milcah, and the father of Iscah” (Genesis 11:29). And Rabbi Yitzḥak said: Iscah is in fact Sarah. And why was she called Iscah? For she saw [sakhta] by means of divine inspiration, as it is stated: “In all that Sarah has said to you, hearken to her voice” (Genesis 21:12). Alternatively, Sarah was also called Iscah, for all gazed [sokhin] upon her beauty.
כיון שילדה שרה אימנו את יצחק כל העקרות נתפקדו כל החרשים נתפקחו וכל הסומים נתפתחו וכל האילמים ניתרפו וכל השוטים נשתפו והיו הכל אומ' הילווי שתפקד שרה אימנו פעם שנייה שניפקד עמה
Pesikta de-Rav Kahana, Sos Asis 22:1
When Sarah gave birth, all the barren women of the nations became pregnant, all the deaf became capable of hearing, all the blind were given sight, all the mutes were cured, and all the madmen became sound of mind. All said: “Would that He take note of Sarah a second time, that we, too, could have been remembered with her!”
Rashi to Genesis 12:4-5
אשר עשו בחרן [THE SOULS] THAT THEY HAD GOTTEN (literally, made) IN HARAN — The souls which he had brought beneath the sheltering wings of the Shechinah. Abraham converted the men and Sarah converted the women and Scripture accounts it unto them as if they had made them (Genesis Rabbah 39:14). However, the real sense of the text is that it refers to the men-servants and to the maidservants whom they had acquired for themselves. The word “עשה” is used here as (in Genesis 31:1), “he has acquired (עשה) all this wealth”, and (Numbers 24:8), “And Israel acquires (עושה) wealth” — an expression for acquiring and amassing.
ר' בנאה הוה קא מציין מערתא כי מטא למערתא דאברהם אשכחיה לאליעזר עבד אברהם דקאי קמי בבא א"ל מאי קא עביד אברהם א"ל גאני בכנפה דשרה וקא מעיינא ליה ברישיה א"ל זיל אימא ליה בנאה קאי אבבא א"ל ליעול מידע ידיע דיצר בהאי עלמא ליכא עייל עיין
Rabbi Bena’a was marking burial caves for the purpose of helping to prevent the contracting of ritual impurity. When he arrived at the cave of Abraham, i.e., the Cave of Machpelah, he encountered Eliezer, the servant of Abraham, who was standing before the entrance. Rabbi Bena’a said to him: What is Abraham doing at this moment? Eliezer said to him: He is lying in the arms of Sarah, and she is examining his head. Rabbi Bena’a said to him: Go tell him that Bena’a is standing at the entrance, so that he should assume an appropriate position to receive a visitor. Eliezer said to him: Let him, i.e., Rabbi Bena’a, enter, since it is known that there is no evil inclination in this higher world, so it is not inappropriate for Rabbi Bena’a to see Abraham and Sarah in this position. He entered, examined the cave in order to measure it, and exited.
