AKJV(i)
15 And the name of the Midianitish woman that was slain was Cozbi, the daughter of Zur; he was head over a people, and of a chief house in Midian.
16 And the LORD spoke to Moses, saying,
17 Vex the Midianites, and smite them:
18 For they vex you with their wiles, with which they have beguiled you in the matter of Peor, and in the matter of Cozbi, the daughter of a prince of Midian, their sister, which was slain in the day of the plague for Peor's sake.
