באור כשדים, a place known nowadays as Ur Kasdim, It could not have had that name at the time Terach and Avraham lived, as כשד the son of Nachor had not been born until later (Genesis 22,22) The offspring of this Kessed became were known as the Kasdim.
Rabbeinu Bahya
ויביאה יצחק האהלה שרה אמו , “Yitzchak brought her into the tent of his mother Sarah.” Here the Torah first refers to Rivkah merely with the pronoun “her, whereas when the same verse continues to report that Yitzchak married Rivkah she is mentioned by name.” The normal procedure should have been to mention Rivkah by name at the beginning of the verse and to refer to her by pronoun when she becomes the subject again in the same verse. Why did the Torah depart from the norm? Perhaps the underlying consideration was to mention Sarah first as she had been her predecessor in that tent and Rivkah had only been born after Sarah had already died and Bethuel had fathered Rivkah (22,23). At that juncture the Torah had seen fit to report Sarah’s death (23,2) which meant that at the time Yitzchak was bound Sarah had already died. Bereshit Rabbah 55,4 said that Yitzchak was 37 years old at that time and that when Sarah heard what was going to happen to him her soul departed and she died. The Torah itself testifies that Yitzchak was 40 years old when he married Rivkah (25,20), which makes Rivkah 3 years old when she was married.
