Numbers 25:18

for they have harassed you with their wiles , with which they beguiled you in the matter of Peor , and in the matter of Cozbi , the daughter of the chief of Midian , their sister , who was killed on the day of the plague on account of Peor .

They treated you as enemies when they deceived you in the Peor incident involving their sister Kozbi, the daughter of a Midianite leader, the woman who was killed when the plague came as a result of that incident.”

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. Numbers 24 Books Numbers 26
