Numbers 25:14-18

MLV(i) 14 Now the name of the man of Israel who was slain, who was slain with the Midianite woman, was Zimri, the son of Salu, a ruler of a fathers' house among the Simeonites. 15 And 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 And Jehovah spoke to Moses, saying, 17 Distress the Midianites and kill* them, 18 for they distress you* with their wiles, with which they have beguiled you* in the matter of Peor and in the matter of Cozbi, the daughter of the ruler of Midian, their sister, who was slain on the day of the plague in the matter of Peor.
