And take it of their half,.... Of the half part of the prey divided to the soldiers:

and give it unto Eleazar the priest for an heave offering of the Lord; by way of thanksgiving for the success and victory, God had given them, by means of which so much booty had fallen into their hands.

Take the sum of the prey that was taken--that is, of the captives and cattle, which, having been first lumped together according to ancient usage (Exo 15:9; Jdg 5:30), were divided into two equal parts: the one to the people at large, who had sustained a common injury from the Midianites and who were all liable to serve: and the other portion to the combatants, who, having encountered the labors and perils of war, justly received the largest share. From both parts, however, a certain deduction was taken for the sanctuary, as a thank offering to God for preservation and for victory. The soldiers had greatly the advantage in the distribution; for a five-hundredth part only of their half went to the priest, while a fiftieth part of the congregation's half was given to the Levites.
