'Leanness' in the Bible

Thus you shriveled me up; it became a witness. And my leanness has risen up against me; it testifies to my face.

So he gave to them their request, but he sent leanness into their souls.

Therefore the Lord, Yahweh of hosts, will send leanness among his sturdy warriors, and a burning like [the] burning of fire will burn under his glory.
