'Charred' in the Bible

For my days are vanishing like smoke; my bones are charred as in a fireplace.

In fact, it is put into the fire as fuel. The fire devours both of its ends, and the middle is charred. Can it be useful for anything?

Even when it was whole it could not be made into a useful object. How much less can it ever be made into anything useful when the fire has devoured it and it is charred!

Pile up the bones, kindle the fire; cook the meat well, mix in the spices, let the bones be charred.
