Bereshis 22:23 Meaning and Commentary

Genesis 22:23

And Bethuel begat Rebekah
Who was to be and was the wife of Isaac; and, for the sake of her genealogy, the above account is given, as Aben Ezra observes, and so Jarchi; and this is observed to pave the way for the history of the chapter; for no notice is taken of any other of Bethuel's children but her, not even of Laban her brother: these eight Milcah did bear, to Nahor, Abraham's brother;
this is observed, and the exact number given, as well as their names, to distinguish them from other children of Nahor he had by another woman, as follows:
