Numbers 31:4 YLT

²  'Execute the vengeance of the sons of Israel against the Midianites -- afterwards thou art gathered unto thy people.'

³  And Moses speaketh unto the people, saying, 'Be ye armed some of you for the host, and they are against Midian, to put the vengeance of Jehovah on Midian;

⁴  a thousand for a tribe -- a thousand for a tribe, to all the tribes of Israel -- ye do send to the host.'

⁵  And there are given out of the thousands of Israel a thousand for a tribe, twelve thousand armed ones of the host;

⁶  and Moses sendeth them, a thousand for a tribe, to the host, them and Phinehas son of Eleazar the priest, to the host; and the holy vessels, and the trumpets of the shouting, in his hand.
