Verse 13. Of the valley - The inhabitants of the city of Jerusalem are here intended. Jerusalem itself was built in part upon the rocky mountain of Zion, but a great part was in the valley, and the higher mountains, about mount Zion, made that mountain itself, in comparison with them, as a valley. The plain - Though also a rock of the plain, that is, near to the plain. Which situation of this place, made the Jews think it to be impregnable.
Verse 14. The forest - By the forest he either means the forest of Lebanon or their houses, made of wood cut out of that forest. And it - And this fire shall not end in the destruction of this city, but in the total destruction of all the country round Jerusalem.
