I. They shall burn their weapons, their bows and arrows, which fell out of their hands (v. 3), their shields and bucklers, their javelins, spears, leading staves, truncheons, and half-pikes, every thing that is combustible. They shall not lay them up in their armouries, nor reserve them for their own use, lest they should be tempted to put a confidence in them, but they shall burn them; not all at once, for a bonfire (to what purpose would be that waste?) but as they had occasion to use them for fuel in their houses, instead of other fire-wood, so that they should have no occasion to take wood out of the field or forests for seven years together (v. 10), such vast quantities of weapons shall there be left upon the open field where the enemy fell, and in the roads which they passed in their flight. The weapons were dry and fitter for fuel than green wood; and, by saving the wood in their coppices and forests, they gave it time to grow. Though the mountains of Israel produce plenty of all good things, yet it becomes the people of Israel to be good husbands of their plenty and to save what they can for the benefit of those that come after them, as Providence shall give them opportunity to do so. We may suppose that when those who dwelt in the cities of Israel came forth to spoil those who spoiled them, and make reprisals upon them, they found upon them silver, and gold, and ornaments; yet no mention is made of any thing particularly that they converted to their own use but the wood of the weapons for fuel, which is one of the necessaries of human life, to teach us to think it enough if we be well supplied with those, though we have but little of the delights and gaieties of it and of those things which we may very well live without. And every time they put fuel to the fire, and warmed themselves at it, they would be put in mind of the number and strength of their enemies, and the imminent peril they were in of falling into their hands, which would help to enlarge their hearts in thankfulness to that God who had so wonderfully, so seasonably, delivered them. As they sat by the fire with their children about them (their fire-side), they might from it take occasion to tell them what great things God had done for them.
