'Heads' in the Bible

But he went to sleep again and had a second dream, in which he saw seven heads of grain, full and good, all on one stem.

And after them came up seven other heads, thin and wasted by the east wind.

And the seven thin heads made a meal of the good heads. And when Pharaoh was awake he saw it was a dream.

And again in a dream I saw seven heads of grain, full and good, coming up on one stem:

And then I saw seven other heads, dry, thin, and wasted by the east wind, coming up after them:

And the seven thin heads made a meal of the seven good heads; and I put this dream before the wise men, but not one of them was able to give me the sense of it.

The seven fat cows are seven years, and the seven good heads of grain are seven years: the two have the same sense.

The seven thin and poor-looking cows who came up after them are seven years; and the seven heads of grain, dry and wasted by the east wind, are seven years when there will be no food.
