Numbers 25:16 WEB

¹⁴  Now the name of the man of Israel that was slain, who was slain with the Midianite woman, was Zimri, the son of Salu, a prince of a fathers' house among the Simeonites.

¹⁵  The 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.

¹⁶  Yahweh spoke to Moses, saying,

¹⁷  Vex the Midianites, and strike them;

¹⁸  for they vex you with their wiles, with which they have deceived 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.
