Genesis 41:32

And for that the dream was doubled unto Pharaoh twice, it is because the thing is established, fully determined upon, by God, and God will shortly bring it to pass. Joseph purposely emphasized the grievousness of the years of famine, that they would be so had as to make people forget the unusually fertile years that had gone before, just as we are inclined to feel any distress very severely and to forget the great blessings of goodness that are ours continually. Joseph's entire manner of speaking, particularly when compared with the helplessness of the Egyptian magicians, was bound to make a deep impression upon the king.
