Numbers 31:4-6

Revised Geneva Translation

⁴ “A thousand of every tribe throughout all the tribes of Israel shall you send to the war.”

⁵ So there were taken out of the thousands of Israel, twelve thousand, prepared to war, of every tribe a thousand.

⁶ And Moses sent them to war, a thousand of every tribe. And he sent them with Phinehas, the son of Eleazar the Priest, to the war. And the holy instruments—that is, the trumpets to blow—were in his hand.
