ציטירנדיקער פּירוש אויף בראשית 18:26

כי עלית משכבי אביך, when you committed that act, חללת יצועי, you defiled my couch; your act prevented me from having any further marital relations with my wife Bilhah. My grandfather explained the expression יתר שאת as an allusion to atonement. [שאת from the root נשא, to elevate, i.e. to forgive as in ונשאתי לכל המקום, “I will forgive the whole place” (Genesis 18,26) Ed.] If so, far from putting down Reuven in his final words to him, Yaakov blessed him by offering his forgiveness at this time for the sin he had committed. against him.
