And Pharaoh said unto Joseph, I [am] Pharaoh,.... Or I am king, which the word Pharaoh signifies, as Josephus says; and that this is not a proper name, but a title of office, seems plain from these words; and the sense either is, that though Pharaoh had raised Joseph to such high honour and dignity, yet he alone was king: or this he said to show his power and authority to do what he had done, and would stand by him, and support him in his office and grandeur:and without thee shall not a man lift up his hand or foot in all the land of Egypt; which is to be taken not in a strict literal sense, but proverbially, signifying, that nothing should be done in the nation of any moment or importance, relating to political affairs, but what was by his order and authority; the hands and feet being the principal instruments of action.
The Targum of Jonathan is,"without thy word (or order) a man shall not lift up his hand to gird on armour, or his foot to mount a horse;''signifying thereby, that all things relating to war and peace should be altogether under his direction.
