Ephraem the Syrian
In addition to everything else that fell under Joseph's authority, the military leaders and the royal nobles were also under his command.
And the king said to Joseph: I am Pharao: without thy commandment no man shall move hand or foot in all the land of Egypt.
וַיֹּ֧אמֶר פַּרְעֹ֛ה אֶל־יוֹסֵ֖ף אֲנִ֣י פַרְעֹ֑ה וּבִלְעָדֶ֗יךָ לֹֽא־יָרִ֨ים אִ֧ישׁ אֶת־יָד֛וֹ וְאֶת־רַגְל֖וֹ בְּכָל־אֶ֥רֶץ מִצְרָֽיִם׃
2 Church Fathers comment on this verse
In addition to everything else that fell under Joseph's authority, the military leaders and the royal nobles were also under his command.
I am Pharaoh: without you no one will be able to act in any way. This signifies that I hold the position of a sovereign ruler, yet I place my authority in your hands. In other words, through the absolute power of a king, I decree that all things will be subject to your command.
