והצעת המטה אמר רבא לא אמרן אלא בפניו אבל שלא בפניו לית לן בה: ומזיגת הכוס שמואל מחלפא ליה דביתהו בידא דשמאלא אביי מנחא ליה אפומא דכובא רבא אבי סדיא רב פפא אשרשיפא

“Making his bed:” Rava said: This refers only to doing so in his presence. But not in his presence, there is no prohibition. “Filling his cup:” Shmuel–his wife passed it to him with her left hand. Abaye—[His wife] placed it on the edge of the wine cask Rava– [His wife placed it] at the head of the couch. Papa—[His wife put it] on his foot-stool.
