Breadcrumb: This time, we'll be ready

There's nothing worse for a besieging, 400,000-man army than to run out of food just as the battles are about to start. This is why Israel prepares for their war by sending 10% of their army as scouts to gather food for their comrades at Gibeah. (Judg. 20:9-10) This also saves the bulk of the army from gathering up crops themselves. In the end, it probably didn't make much of a difference, as the battle only lasted three days. Still, it's good to know that if things had gone on longer, at least the army wouldn't die of starvation.
