Numbers 25:15, 18

And the name of the Midianitish woman that was slain was Cozbi, the daughter of Zur; he was head of the people of a fathers’ house in Midian.

for they vex you with their wiles, wherewith they have beguiled you in the matter of Peor, and in the matter of Cozbi, the daughter of the prince of Midian, their sister, who was slain on the day of the plague in the matter of Peor.
