'Thin' in the Bible

Then behold, seven ears [of grain], thin and dried up by the east wind, sprouted after them.

Then the thin ears swallowed the seven plump and full ears. And Pharaoh awoke, and it was a dream.

Yet when they had devoured them, it could not be detected that they had eaten them, because they were still as thin and emaciated as before. Then I awoke [but again I fell asleep and dreamed].

and lo, seven [other] ears, withered, thin, and scorched by the east wind, sprouted after them;

and the thin ears devoured the seven good ears. Now I told this to the magicians and soothsayers, but there was no one who could explain it [to me].”

The seven thin and ugly cows that came up after them are seven years; and also the seven thin ears, dried up and scorched by the east wind, they are seven years of famine and hunger.
