Genesis 41:16, 32, 54

Joseph answered Pharaoh, “It is not in me; God will give Pharaoh a favorable answer.”

And the doubling of Pharaoh’s dream means that the thing is fixed by God, and God will shortly bring it about.

and the seven years of famine began to come, as Joseph had said. There was famine in all lands, but in all the land of Egypt there was bread.
