10 And Jehovah spoke to Moses, saying, 11 Phinehas, 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. 12 Therefore say, Behold, I give unto him my covenant of peace! 13 And he shall have it, and 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.
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.
