Following the war with Midian, the spoils are divided among the nation. Moses collects a portion from the half belonging to the Israelites who stayed behind, transferring it to the Levites. A striking difference emerges between this collection and the tax taken from the soldiers who fought on the front lines. Previously, the exact numbers of the soldiers' tax were carefully recorded for every category of spoil. However, the specific numbers for the civilians' tax are left unrecorded, even though their overall contribution is significantly larger, being one in fifty compared to the soldiers' one in five hundred.
This distinction serves to honor the soldiers [פני דוד]. The fighters risked their lives in battle and willingly gave a portion of what they had earned through intense physical effort. To honor their sacrifice, their contribution is recorded with precision. In contrast, the rest of the nation remained safely in their tents, receiving half the spoils without any effort as a gift from Heaven. Because of this, their contribution does not receive the same level of detail. The collection itself includes humans and animals, a general category that encompasses all types of living spoils [אבן עזרא].
This portion is handed over to the Levites, which raises a question regarding why they receive their share specifically from the half belonging to the civilian population. The tribe of Levi also sent a thousand warriors to the battle and could have simply kept the spoils brought back by their own representatives. This unique method of distribution is likely intended to establish a sense of equality among all the tribes regarding their rights to the spoils of war [ברכת אשר על התורה].
As for how these assets are distributed within the tribe of Levi itself, Moses acts strictly according to God's commands. Moses possesses a clear tradition and direct instruction from God, guiding him on exactly how to allocate and manage this massive collection among the various Levite families [העמק דבר].
