Let's Slay some Virgins Levites?

Nbrs Ch.31 Vrs.17-8

Now therefore kill every male among the little ones, and kill every woman that hath known man by lying with him.

Nbrs. ch.31 vrs. 25-29

And the LORD spoke unto Moses, saying, Take the sum of the prey that was taken, both of man and of beast, thou, and Eleazar the priest, and the chief fathers of the congregation: and divide the prey into two parts, between all the congregation. And levy a tribute unto the LORD of the men of war which went out to battle: one soul of five hundred, both of the persons, and of the beeves, and of the asses, and of the sheep. Take if of their half, and give it unto Eleazar the priest, for a heave offering to the LORD.


So after much researching and peering into the text again and again I've found that the heave offering does not require nor does it usually involve a sacrifice (death). This whole time I've been understanding this passage to mean that The Lord had Moses command Eleazar to Sacrifice 32 virgin Midianites to the lord, when in actuality The Lord was  giving unto the priests a tithe of the salvages of war which their people had know way of obtaining (due to the act that the Levitical people were priests, not warriors, unlike the rest of the twelves tribes of Israel)
