'Cast into the Fire' in the Bible

Let burning coals fall upon them: let them be cast into the fire; into deep pits, that they rise not up again.

Behold, it is cast into the fire for fuel; the fire devours both the ends of it, and the middle of it is burned. Is it fit for any work?

And now also the ax is laid unto the root of the trees: therefore every tree which brings not forth good fruit is hewn down, and cast into the fire.

Every tree that brings not forth good fruit is hewn down, and cast into the fire.

And now also the ax is laid unto the root of the trees: every tree therefore which brings not forth good fruit is cut down, and cast into the fire.
