Numbers 25:17

15The name of the Midianite woman who was slain was Cozbi, the daughter of Zur. He was head of the people of a fathers’ house in Midian.

16The LORD spoke to Moses, saying,

17“Harass the Midianites, and strike them;

18for they harassed you with their wiles, wherein they have deceived you in the matter of Peor, and in the incident regarding Cozbi, the daughter of the prince of Midian, their sister, who was slain on the day of the plague in the matter of Peor.”
