Numbers 31:1-6

1Then the Lord said to Moses,

2“On behalf of the people of Israel, take revenge on the Midianites for leading them into idolatry. After that, you will die and join your ancestors.”

3So Moses said to the people, “Choose some men, and arm them to fight the Lord’s war of revenge against Midian.

4From each tribe of Israel, send 1,000 men into battle.”

5So they chose 1,000 men from each tribe of Israel, a total of 12,000 men armed for battle.

6Then Moses sent them out, 1,000 men from each tribe, and Phinehas son of Eleazar the priest led them into battle. They carried along the holy objects of the sanctuary and the trumpets for sounding the charge.
