Genesis 41:28-32

This is the thing which I have spoken unto Pharaoh: What God is about to do he sheweth unto Pharaoh.

Behold, there come seven years of great plenty throughout all the land of Egypt:

And there shall arise after them seven years of famine; and all the plenty shall be forgotten in the land of Egypt; and the famine shall consume the land;

And the plenty shall not be known in the land by reason of that famine following; for it shall be very grievous.

And for that the dream was doubled unto Pharaoh twice; it is because the thing is established by God, and God will shortly bring it to pass.
