Discussing Klal Yisrael‘s entry into battle, in Parashas Ki Tzeitzei (Devarim 21:10), the Torah does not seem to outline any specific means of aggressive attack. The Torah simply states, “When you go forth to war against your enemies, and Hashem your G-d will deliver them into your hands.” Why is there such a disparity between the two parshios dealing with waging war on the enemy?
The Kotzker Rebbe z.l. distinguishes between two contrasting types of war. He suggests that the term “war” is actually an allusion to man’s constant battle with the yetzer hora, evil inclination. The differential is determined by noting who has initiated the battle. In this parsha the Torah states, “If you will come into war,” while in Sefer Devarim the Torah states, “When you go forth.” One who “goes forth” and initiates the battle against the yetzer hora, is assured of emerging triumphant. If, however, one allows the yetzer hora to approach him, to “oppress him in his own land,” to get a foothold in his behavior and personality, then victory will be more elusive. He will have to battle with much more resolution in order to triumph over the enemy. Such a battle must include astute strategy, sounding of alarms, and crying out to Hashem, for only with His help can man succeed.
