Kommentar zu Bereschit 47:14

בשבי אשר הם שוברים FOR THE CORN WHICH THEY BOUGHT — they gave him the money.

AND JOSEPH GATHERED UP ALL THE MONEY, etc. Scripture relates this and goes on to complete the subject in this entire section in order to make known Joseph’s excellence in wisdom, in understanding, and in knowledge,²⁴¹Exodus 31:3. and that he was a faithful man²⁴²Proverbs 20:6. in that he brought all money into Pharaoh’s house and did not accumulate for himself treasures of money and secret hiding places for wealth in the land of Egypt, or send it to the land of Canaan. Instead, he gave all money to the king who trusted him and purchased the land for him, and even the bodies of the Egyptians. Through this endeavor, he found grace even in the eyes of the people, for it is G-d Who causes those who fear Him to prosper.

ויבא יוסף את הכסף ביתה פרעה, because he did not permit himself to recompense himself on his own accord without being given his compensation by Pharaoh
