Numbers 31:4-6

International Standard Version

⁴ Send 1,000 men to war from every tribe throughout all of Israel.” ⁵ So 1,000 men from every tribe—12,000 from the thousands of Israel—were mustered and equipped for war.

⁶ Moses sent 1,000 men from every tribe to fight against them, along with Eleazar’s son Phinehas, in whose hands were the articles of the sanctuary and trumpets to sound battle alarms.
