Numbers 25:17-18

BBE(i) 17 Take up arms against the Midianites and overcome them; 18 For they are a danger to you with their false ways, causing sin to come on you in the question of Peor, and because of Cozbi, their sister, the daughter of the chief of Midian, who was put to death at the time of the disease which came on you because of Peor.
