And they that dwell in the cities of Israel shall go forth, and shall set on fire and burn the weapons, both the shields and the bucklers, the bows and the arrows, and the handstaves, and the spears, and they shall burn them with fire seven years: And shall set on fire - the weapons - The Israelites shall make bonfires and fuel of the weapons, tents, etc., which the defeated Syrians shall leave behind them, as expressive of the joy which they shall feel for the destruction of their enemies; and to keep up, in their culinary consumption, the memory of this great event.
They shall burn them with fire seven years - These may be figurative expressions, after the manner of the Asiatics, whose language abounds with such descriptions. They occur every where in the prophets. As to the number seven it is only a certain for an indeterminate number. But as the slaughter was great, and the bows, arrows, quivers, shields, bucklers, handstaves, and spears were in vast multitudes, it must have taken a long time to gather them up in the different parts of the fields of battle, and the roads in which the Syrians had retreated, throwing away their arms as they proceeded; so there might have been a long time employed in collecting and burning them. And as all seem to have been doomed to the fire, there might have been some found at different intervals and burned, during the seven years here mentioned. Mariana, in his History of Spain, lib. xi., c. 24, says, that after the Spaniards had given that signal overthrow to the Saracens, a.d. 1212 they found such a vast quantity of lances, javelins, and such like, that they served them for four years for fuel. And probably these instruments obtained by the Israelites were used in general for culinary firewood, and might literally have served them for seven years; so that during that time they should take no wood out of the fields, nor out of the forests for the purpose of fuel, Ezekiel 39:10.
