Numbers 25:14-18

14Now the name of the Israelite who was killed, who was killed with the Midianite woman, was Zimri the son of Salu, a leader of a father’s house among the Simeonites.

15And the name of the Midianite woman who was killed was Cozbi the daughter of Zur; he was head of the people of a father’s house in Midian.

16Then the Lord spoke to Moses, saying:

17“Harass the Midianites, and attack them;

18for they harassed you with their schemes by which they seduced you in the matter of Peor and in the matter of Cozbi, the daughter of a leader of Midian, their sister, who was killed in the day of the plague because of Peor.”
