Genesis 41:33

Let Pharaoh look out a man It was not presumption in Joseph to offer this advice to Pharaoh, considering that God, by him, had given Pharaoh the fore-knowledge of what was about to come to pass, and what greatly concerned both him and his whole kingdom. Indeed, the advice was only that he should make a practical and proper use of the revelation now made to him. Joseph, in giving this counsel, could have no view to his own advancement to this office; as any thing of that kind, at that time, when he was just brought out of prison, and did not know but he must be sent back thither, must have appeared highly improbable.
