'Bones' in the Bible

From heaven he sent fire, into my bones he let it descend. He spread out a net for my feet; he turned me back, he gave me devastation, fainting all day.

He has worn out my flesh and skin, he has broken my bones.

[Now] their appearance is blacker than soot, they are not recognized in the streets; their skin has shriveled on their bones, it has become dry like wood.
