Numbers 31:2-6

Leeser(i) 2 Execute the vengeance of the children of Israel on the Midianites, after which thou shalt be gathered unto thy people. 3 And Moses spoke unto the people, saying, Arm from yourselves some men for the army, and let them go against the Midianites, to execute the vengeance of the Lord on Midian. 4 A thousand each for every tribe, of all the tribes of Israel, shall ye send to the army. 5 And there were levied out of the thousands of Israel, a thousand of every tribe, twelve thousand armed for the army. 6 And Moses sent them, a thousand of every tribe, to the army; them and Phinehas the son of Elazar the priest, to the army, with the holy vessels, and the trumpets for blowing the alarm in his hand.
