Numbers 31:5
So there were delivered out of the thousands of Israel, a thousand of every tribe, twelve thousand armed for war.
So they were delivered out of the thousands of Israel,.... Several thousands very probably offered themselves voluntarily to go to the war, or however were summoned together on this account, and out of them the following number was delivered of picked and chosen men:
a thousand of every tribe, twelve thousand armed for war; which was but a small number to go against so considerable a nation and people; but this was done to show that the war was of the Lord, he would fight the battle, and give them victory, it being the same to him to do it with few as with many; and to encourage the people of Israel to believe the Lord would give them success against their many and powerful enemies in the land of Canaan, on the borders of which they now were.
