Sforno on Genesis 41:28/ספורנו על בראשית מ״א:כ״ח

1הוא הדבר, it is the forthcoming famine which I described as the advance information given by G’d to Pharaoh in order to ward off the danger that the famine would destroy Egypt.

2הראה את פרעה, the years of plenty, to give you an idea of how to save your people from the devastating effects of the famine.
