Commentaire sur Les Nombres 31:3

וידבר משה וגו׳ AND MOSES SPAKE etc. — Although he had heard (v. 2) that his death was associated with this matter, he did it gladly and did not delay (Sifrei Bamidbar 157:2).

וידבר משה…החלצו מאתכם, Moses said.. "mobilise from amongst you, etc." The word לאמור in this verse is puzzling. To whom were the people supposed to relay what Moses told them? Furthermore, why did Moses use the expression החלצו instead of the formulation Moses used in Exodus 17,9 when he said to Joshua: בחר לנו אנשים, "choose some men for us, etc.?" Why did he not order Pinchas to do what he had ordered Joshua to do at that time instead of addressing his command to the people at large? Another peculiarity in this verse are the words ויהיו על מדין "so that they will be against Midian." Moses should have said: "so that they will do battle against Midian." Moreover, why did Moses change G'd's instructions? G'd had told Moses נקם נקמת בני ישראל, "avenge the vengeance of the Israelites," whereas Moses told the people to exact "G'd's vengeance," i.e. לתת נקמת השם? Besides, why did Moses not send a large army but selected only 1.000 men per tribe? Who had given him authority to send such a small force of soldiers against a numerically far superior people [governed by 5 kings Ed.]? When you consider that 32.000 girls who were still virgins were left you can arrive at some idea how many there must have been originally.

החלצו מאתכם, “mobilize from amongst yourselves, etc.” It is as if Moses had said: “gird your pioneers, your vanguard, (with their swords).” The words used here reflect an eagerness on the part of Moses to discharge his part in this commandment although G’d had told him that its fulfillment would bring about his death shortly thereafter. Tanchuma Mattot 4 points out the contrast between Moses and Joshua in this matter. When Joshua faced 31 Canaanite kings he said to himself: “if I slay them I will die shortly thereafter just as Moses died shortly after the Midianites were defeated.” What did Joshua do? He commenced with attacking one of the Canaanite kings and then delayed following up on his success as we know from Joshua 11,18: “Joshua was engaged for many years in battling all these kings.” When G’d observed this He told him: “because you did this in order to prolong your life I will deduct 10 years from the life span I had allocated to you originally. You should have lived to 120 years as did your teacher Moses. Now you will live to be only 110 years.” This is the meaning of Proverbs 19,21: “Many designs are in a man’s mind, but it is the Lord’s plan that is accomplished.“
