10 And Jehovah speaketh unto Moses, saying, 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.'
Matthew Henry's Commentary on Numbers 25:10-13
Commentary on Numbers 25:6-15
(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.
