As the fire burneth a wood, and as the flame setteth the mountains on fire;
Ver. 14. As the fire burneth a wood] Maxime quando a vento flabellatur, when blown up by a fierce wind it soon turneth a wood into a waste.
And as the flame setteth, the mountains on fire] Those sulphury mountains, such as Etna, Vesuvius, Peitra mala, a mountain in the highest part of the Apennines, which perpetually burneth, say travellers, Il Mercurio Italico, 178.
