And Joseph was thirty years old when he stood before Pharaoh king of Egypt. And Joseph went out from the presence of Pharaoh, and went throughout all the land of Egypt. Joseph was thirty years old - As he was seventeen years old when he was sold into Egypt, Genesis 37:2, and was now thirty, he must have been thirteen years in slavery.
Stood before Pharaoh - This phrase always means admission to the immediate presence of the sovereign, and having the honor of his most unlimited confidence. Among the Asiatic princes, the privilege of coming even to their seat, of standing before them, etc., was granted only to the highest favorites.
