(12) My covenant of peace.--Phinehas, as one who was zealous for the honour of God and of the house of the Lord, was a fitting type of Christ, in whom the prediction of the Psalmist received its accomplishment, "The zeal of thine house hath eaten me up" (Psalm 69:9; John 2:17). The covenant of grace is described in Isaiah 54:10 and in Malachi 2:5 as the covenant of peace.

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.Wherefore say,.... Moses is bid to tell what follows to Phinehas himself, for his comfort and encouragement, and to the people of Israel, that they might take notice of it, and give him honour and respect, as one highly esteemed by the Lord:

behold, I give unto him my covenant of peace; not only hereby assuring him that he had nothing to fear from the brethren and relations of the person he had slain, as Aben Ezra; but that he should enjoy all peace and happiness, external, internal, and eternal: Baal Hatfurira on the place says, that "Shalom", peace, is by geometry, or numerically, the Messiah; who is the peace, the peace maker, and peace giver, and in whom all the blessings of grace and peace are: and if this covenant is the same with the covenant of the priesthood in the next verse, it may be so called, because the priests had a peculiar nearness to God, and enjoyed his friendship, favour, and peace with him, and because the right administration of their office was the means of peace between God and his people; in this also Phinehas was a type of Christ; the covenant of grace made with him is called the covenant of peace, Isaiah 54:10 for in this covenant the scheme of peace and reconciliation was formed, agreed to, and settled; Christ was appointed the peace maker, which he agreed to be; and in consequence of it was sent and obtained peace by the blood of his cross, which is published in the everlasting Gospel, called therefore the Gospel of peace.
