Numbers 31:2-6

KJV(i) 2 Avenge the children of Israel of the Midianites: afterward shalt thou be gathered unto thy people. 3 And Moses spake unto the people, saying, Arm some of yourselves unto the war, and let them go against the Midianites, and avenge the LORD of Midian. 4 Of every tribe a thousand, throughout all the tribes of Israel, shall ye send to the war. 5 So there were delivered out of the thousands of Israel, a thousand of every tribe, twelve thousand armed for war. 6 And Moses sent them to the war, a thousand of every tribe, them and Phinehas the son of Eleazar the priest, to the war, with the holy instruments, and the trumpets to blow in his hand.
