I also dreamed that I saw seven heads of grain which were full and ripe, growing on one stalk.
Then seven heads of grain sprouted, thin and scorched by the desert wind,
and the thin heads of grain swallowed the full ones. I told the dreams to the magicians, but none of them could explain them to me."
Joseph said to the king, "The two dreams mean the same thing; God has told you what he is going to do.
The seven fat cows are seven years, and the seven full heads of grain are also seven years; they have the same meaning.
The seven thin cows which came up later and the seven thin heads of grain scorched by the desert wind are seven years of famine.
It is just as I told you - God has shown you what he is going to do.
There will be seven years of great plenty in all the land of Egypt.
After that, there will be seven years of famine, and all the good years will be forgotten, because the famine will ruin the country.
The time of plenty will be entirely forgotten, because the famine which follows will be so terrible.
The repetition of your dream means that the matter is fixed by God and that he will make it happen in the near future.
