The woman’s name was Cozbi; she was the daughter of Zur, the leader of a Midianite clan.

because they assaulted you with deceit and tricked you into worshiping Baal of Peor, and because of Cozbi, the daughter of a Midianite leader, who was killed at the time of the plague because of what happened at Peor.”
