Genesis 24:36

“And Sarah, my master’s wife, etc.] Who must be well known to this family, by name at least, being, as is generally supposed, the sister of Milcah, Nahor’s wife, and Bethuel’s mother; the same bare a son to my master when she was old; even when ninety years of age, (<011717>Genesis 17:17); this is mentioned because it was an extraordinary thing, and an instance of divine power and of the favour of God; and this son of their old age must be very dear unto Abraham, as it follows: and unto him hath he given all that he hath; by his will: Jarchi says, the servant had now the schedule of all in his hands, which he showed; but this is mere conjecture.”
