Numbers 25:10-18 - The Aftermath
10 And the LORD spake unto Moses, saying, 11 "Phinehas the son of Eleazar the son of Aaron the priest, hath turned mine anger away from the children of Israel, because he was jealous for my sake among them; that I had not consumed the children of Israel in my jealousy. 12 Wherefore, say, 'Behold, I give unto him my covenant of peace, 13 and he shall have it and his seed after him, even the covenant of the priest's office forever, because he was jealous for his God's sake and made an atonement for the children of Israel.'"
14 The name of the Israelite which was smitten with the Midianitish woman, was Zimri the son of Salu, a lord of an ancient house among the Simeonites. 15 And the name of the Midianitish woman was Cozbi, the daughter of Zur and head over the people of an ancient house in Midian.
16 And the LORD spake unto Moses, saying, 17 "Vex the Midianites and smite them, 18 for they have troubled you with their wiles with thee, which they have beguiled you, through Peor and through their sister Cozbi the daughter of a lord in Midian, which was slain in the day of the plague for Peor's sake."
