'Lean fleshed' in the Bible

And him thought that seven other cows came up after them out of the river; evil favored and lean fleshed and stood by the other upon the brink of the river.

And the evil favored and lean fleshed cows ate up the seven well favored and fat cows: and he awoke therewith.

And then seven other cows came up after them, poor and very evil favored and lean fleshed: so that I never saw their like, in all the land of Egypt, in evil favoredness.
