1 Samuel 4:10

Israel fled every man into —better to— his tent. Their camp stood them this time in no stead. It was stormed by the Philistines, and the whole army fled in confusion. In those days the Israelites dwelt in tents, and to flee "every man to his tent" means that they fled away in every direction, each to his own home. It is in this indiscriminate flight that an army suffers most. As long as men keep together the loss is comparatively slight. But now, thus utterly broken, there fell of Israel thirty thousand footmen— a terrible slaughter. They are called footmen because the Israelites had neither cavalry nor chariots.
