'Burnt' in the Bible

For the mountains will I take up weeping and wailing, and for the pastures of the wilderness, a lamentation; for they are burnt up, so that none passeth through them; and the voice of the cattle is not heard. Both the fowl of the heavens and the beasts are fled; they are gone.

Who is a wise man, that he may understand this? and he to whom the mouth of Jehovah hath spoken, that he may declare it? Why is the land perished, burnt up like a wilderness, so that none passeth through?

and the passages are seized, and the reedy places are burnt with fire, and the men of war are affrighted.
