AND ABRAHAM WAS OLD, WELL STRICKEN IN AGE. Scripture reiterates [Abraham’s old age although it has already mentioned it]⁵⁷Above, 18:11. in order to inform us of the reason that he adjured his servant. Thus Scripture says that because Abraham saw himself to be very old and he thought that if he will send the servant to the land of his origin, perhaps before the messenger would return, he will have gone to his long home,⁵⁸Ecclesiastes 12:5. he therefore adjured his servant — whose counsel Isaac would follow since he ruled over all that he had⁵⁹Verse 2 here. — that he should not take for him a wife from the daughters of Canaan.

But here it says that he was very old for already he was ba bayamim [literally: “he had come in days” — past tense], just as: Thy brother ‘ba’ (came) with subtlety.⁶⁴Further, 27:35.
