'Bad looking' in the Bible

Then seven bad-looking, thin cows were coming up after them from the Nile, and they stood beside the other cows at the edge of the river.

The bad-looking, thin cows ate the seven fine-looking, fat cows. Then Pharaoh woke up.

Then seven other cows came up after them; they were scrawny, very bad-looking, and lean. I had never seen such bad-looking cows as these in all the land of Egypt!

The lean, bad-looking cows ate up the seven fat cows.

When they had eaten them, no one would have known that they had done so, for they were just as bad-looking as before. Then I woke up.

The seven lean, bad-looking cows that came up after them represent seven years, as do the seven empty heads of grain burned with the east wind. They represent seven years of famine.
