'Bones' in the Bible

“From on high He sent fire into my bones,And it prevailed over them.He has spread a net for my feet;He has turned me back;He has made me desolate,Faint all day long.

He has caused my flesh and my skin to waste away,He has broken my bones.

Their appearance is blacker than soot,They are not recognized in the streets;Their skin is shriveled on their bones,It is withered, it has become like wood.
