Mishnayos Sotah Perek 8 Mishnah 6

The mishna continues its discussion. The verse states: “And it shall be, when the officers conclude speaking to the people, that captains of legions shall be appointed at the head of the people” (Deuteronomy 20:9). The mishna adds: As well as at the rear of the people. The officers station guards [zekifin] in front of them, and other guards behind them, and they have iron rods [kashilin] in their hands. And with regard to anyone who attempts to turn back and flee from the war, the guard has license to beat [lekape’aḥ] his legs because the beginning of fleeing is a downfall on the battlefield, as it is stated: “Israel has fled before the Philistines, and there has been also a great slaughter among the people” (I Samuel 4:17), and likewise it says further on: “And the men of Israel fled from before the Philistines, and fell down slain in Mount Gilboa” (I Samuel 31:1).
