Numbers 25:7-15

7And when Phinehas, the son of Eleazar, the son of Aaron the priest, saw it, he rose up from the midst of the congregation, and took a spear in his hand; 8and he went after the man of Israel into the pavilion, and thrust both of them through, the man of Israel, and the woman through her body. So the plague was stayed from the children of Israel. 9And those that died by the plague were twenty and four thousand.

10And Jehovah spake unto Moses, saying, 11Phinehas, the son of Eleazar, the son of Aaron the priest, hath turned my wrath away from the children of Israel, in that he was jealous with my jealousy among them, so that I consumed not the children of Israel in my jealousy. 12Wherefore say, Behold, I give unto him my covenant of peace: 13and it shall be unto him, and to his seed after him, the covenant of an everlasting priesthood; because he was jealous for his God, and made atonement for the children of Israel.

14Now the name of the man of Israel that was slain, who was slain with the Midianitish woman, was Zimri, the son of Salu, a prince of a fathers’ house among the Simeonites. 15And the name of the Midianitish woman that was slain was Cozbi, the daughter of Zur; he was head of the people of a fathers’ house in Midian.
