Numbers 25:18

¹⁶  And the LORD spake unto Moses, saying,

¹⁷  Vex the Midianites, and smite them:

¹⁸  For they vex you with their wiles, wherewith 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.
