Numbers 31:5-7

Complete Jewish Bible

⁵ So out of the thousands of people in Isra’el, a thousand armed men from each tribe, 12,000 altogether, were mustered for war. ⁶ Moshe sent them, a thousand from each tribe, to the war; he sent them and Pinchas the son of El‘azar the cohen to the war, with the holy utensils and the trumpets for sounding the alarm in his care.

⁷ They fought against Midyan, as Adonai had ordered Moshe, and killed every male.
