Midrasz do Rodzaju 47:26

R. Malai. in the name of R. Isaac, said further: "Since the day when Joseph departed from his brothers, he tasted no wine, as it is written (Gen. 47, 26.) And on the crown of the head of him who was separated from his brother." R. Jose b. Chanina said: "The brothers of Joseph also did not taste wine, for it is said (Ib. 43, 34.) And they drank and were merry with him. We infer that without him they did not drink." But the former (R. Malai) holds this refers to being drunk but not to tasting. R Malai further said: "As a reward [due to Aaron] for, And when he sees thee, he shall be glad in his heart (Ex. 4, 14) , he was given the Choshen Hamishpat on his heart."
