'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 devoureth both the ends of it, and the midst of it is burned. Is it meet for any work?

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

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

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