Kommentar zu Bereschit 29:21

מלאו ימי MY DAYS ARE FULFILLED — which my mother told me to remain with you. And another explanation is: MY DAYS ARE FULFILLED for I am now eighty-four years old and when shall I beget twelve tribes? That is what he meant by adding “that I may go in unto her”; for surely even the commonest of people would not use such an expression. But he said this because his mind was intent upon having issue (to fulfil his mission of rearing children who would carry on the religious traditions of his fathers) (Genesis Rabbah 70:18).

FOR MY DAYS ARE FULFILLED. This means “the time which my mother told me to remain away from home.” Another explanation is: For my days are fulfilled — “I am now eighty-four years old and when shall I beget twelve tribes?” These are the words of Rashi.

כי מלאו ימי, “I have served you for seven years.”
