Nachor son of Terach died in the fortieth year of Yitzchak's life [(this is Year 2088)]. And all the days of Nachor were one hundred seventy-two years, and he was buried in Charan. Avraham mourned him for many days. And Avraham sent Eliezer to take a wife for Yitzchak.
And when he went, Avraham sent to the house of Shem and Ever to bring Yitzchak, and Eliezer went to Charan. [(Sefer HaYashar)] From Kiryat Arba to Charan is a journey of seventeen days, but in two hours he came to Charan, etc., for it says, "And I came today to the well," etc. He rose early in the morning and saw the angel standing and waiting, and said, "Do not delay me," etc. And so that the servant would not be alone with the maiden at night, the earth contracted.
At six hours of the day the servant left Charan and in two hours he came to Chevron toward evening, and Yitzchak went out to pray the Minchah (afternoon) prayer. [(Pirkei DeRabbi Eliezer chapter 16) And in the Midrash, section 109, at two hours of the day he left Charan and the earth contracted, etc.] And they gave him Rivkah, and she was ten years old. And they sent with her Devorah her nurse, daughter of Utz, and gave her silver and gold and servants and maidservants.
And Yitzchak was forty years old when he took Rivkah [(this is Year 2088)] [(Sefer HaYashar)]. Three years after Sarah's death he took Rivkah [(Pirkei DeRabbi Eliezer chapter 32). In the Seder Olam and in Tosefot on the chapter "HaBa Al Yevimto" (Sanhedrin 69b), and in the Midrash at the beginning of Toldot, she was three years old. And in Masechet Sofrim, end of chapter 21, Rivkah was three years and three days old (for she was born at the time of the Akeidah, Bereishit Rabbah, chapter 57).
And in Tosefot there, according to one opinion she was fourteen years old, and according to Bereishit Rabbah there that Rivkah was born at the time of the Akeidah and Yitzchak was forty when he married her, there are therefore different opinions as to how old she was (see Year 2085), and it depends on how old Yitzchak was at the time of the Akeidah. According to the opinion that Yitzchak was twenty-six at the Akeidah, it follows that Rivkah was fourteen years old when Yitzchak married her at age forty.
And according to the opinion that Yitzchak was thirty-seven, it follows that Rivkah was three when Yitzchak married her.]
