ברך את אברהם בכל [THE LORD HAD] BLESSED ABRAHAM IN ALL THINGS — The numerical value of the word בכל is equal to that of בן (a son) — suggesting that God had blessed Abraham with a son and since he had a son he had to find him a wife.

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.
In Bereshith Rabbah,⁶⁰48:19. the Rabbis said: “Here⁶¹That is, above, 18:11, where Scripture says, Now Abraham and Sarah were old. it was old age combined with vitality; further on⁶²That is, in the verse before us. it was old age without vitality.” By this the Rabbis wanted to explain that ba’im [literally: “coming” in days — mentioned above]⁵⁷Above, 18:11. — means the beginning of the days of old age, as the word ba’im indicates the present, just as, ‘Haba’im’ (those that come) in at these gates.⁶³Jeremiah 7:2. 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.

1 He was advanced in years. This is to say, the time had come to marry off his son during his lifetime.
