Numbers 25:11-13
11 'Phinehas, son of Eleazar, son of Aaron the priest, hath turned back My fury from the sons of Israel, by his being zealous with My zeal in their midst, and I have not consumed the sons of Israel in My zeal. 12 'Therefore say, Lo, I am giving to him My covenant of peace, 13 and it hath been to him and to his seed after him a covenant of a priesthood age-during, because that he hath been zealous for his God, and doth make atonement for the sons of Israel.'

(Read Numbers 25:6-15)
Phinehas, in the courage of zeal and faith, executed vengeance on Zimri and Cozbi. This act can never be an example for private revenge, or religious persecution, or for irregular public vengeance.
