'Burned' in the Bible

In whose hand is the instrument with which he will make clean his grain; he will put the good grain in his store, but the waste will be burned up in the fire which will never be put out.

And when the sun was high, it was burned; and because it had no root it became dry and dead.

As then the evil plants are got together and burned with fire, so will it be in the end of the world.
