Numbers 31:3-6

MSTC^{(i) 3} And Moses spake unto the folk, saying, "Harness some of you unto war, and let them go upon the Midianites and avenge the LORD of the Midianites. ⁴ Ye shall send unto the war a thousand of every tribe throughout all the tribes of Israel." ⁵ And there were taken, out of the thousands of Israel, twelve thousand prepared unto war: of every tribe a thousand. ⁶ And Moses sent them — a thousand of every tribe, with Phinehas the son of Eleazar the priest — to war, and the holy vessels and the trumpets to blow with, in his hand.
