Whereas Moses, disregarding the expected consequences of the war upon himself, gladly went into battle, Israel did not want to obey his summons to war. The people of whom Moses had on one occasion said, "They be almost ready to stone me," when they now learned that their leader Moses was to die at the end of this war, tried to evade it, saying that they preferred to forego impending victory rather than to lose their leader, and each one hid himself, so as not to be picked out for this war.
God therefore bade Moses cast lots to decide their going into battle, and those whose lots were drawn had to follow the call to arms even against their will. Moses' summons to battle was as follows: "Arm ye men from among you for the war, to execute the Lord's vengeance on Midain." Moses spoke of the Lord's revenge, whereas God designated this war against Midian as Israel's revenge. For Moses said to God: "Lord of the world!
If we had worshipped the stars and planets, the Midianites should not have hated us, they hate us only on account of the Torah and the commandments that Thou hast given us, hence must Thou avenge Thyself of them."
