Numbers 25:14-18

14The name of the slain Israelite man, who was struck dead with the Midianite woman, was Zimri son of Salu, the leader of a Simeonite family.

15The name of the slain Midianite woman was Cozbi, the daughter of Zur, a tribal head of a family in Midian.

16The Lord told Moses,

17“Attack the Midianites and strike them dead.

18For they attacked you with the treachery that they used against you in the Peor incident. They did the same in the case involving their sister Cozbi, daughter of the Midianite leader who was killed the day the plague came at Peor.”
