Ibn Ezra on Genesis 39:22/אבן עזרא על בראשית ל״ט:כ״ב

אואת כל אשר עושים. יש אומרים כי היה מתעסק באומנות שיחיה ממנה, כאשר הי' עושים האסורים, והקרוב אלי שפירושו כל אשר הי' צריכים כאילו היה הוא העושה כי פקיד היה עליהם, והפסוק הבא אחריו לעד:
1AND WHATSOEVER THEY DID THERE, HE WAS THE DOER OF IT. Some interpret this to mean that Joseph, like all the other prisoners, was engaged in work to support himself.11 However, I believe that the meaning of our verse is: and whatsoever they had to do there he was, as it were, the doer of it, because he was their supervisor. The next verse bears out the latter interpretation.12, which implies that Joseph did not actually do any work, but supervised the others.
