And the Lord spake unto Moses. In these words God makes it appear that He was the author of the death (of Zimri and Cozbi;) not only because He was thus propitiated towards the people, but because He calls the zeal of Phinehas His own. [1] It will, however, accord equally well whether we take it actively or passively, viz., either that Phinehas was inflamed with zeal to vindicate God's glory, or that he took upon him the zeal of God Himself. Whichever be preferred, God refers to Himself what was done by Phinehas. When He declares that He was appeased by the punishment inflicted, let us not imagine that there was a meritorious satisfaction, whereby the Papists feign that their punishments are redeemed before God. For although the just chastisements of sin are sacrifices of sweet savor, they are by no means expiations to reconcile God. Besides, there is no question here of compensation, but what is meant is, that it was a means of appeasing God, when the ungodliness of the people which had, as it were, fanned up His wrath into a flame, was repressed by this severe correction. Thus, in Psalm 106, the atonement is ascribed not to the act of Phinehas, but only to his prayer, [2] because, in right of his priesthood, he had humbly interceded for the people. At the same time, the statement of Paul is true, that those are not judged by God who voluntarily judge themselves, (1-Corinthians 11:31,) since, by their penitence, they in a manner prevent this judgment. A perpetual priesthood is promised to Phinehas as his reward. If any object, that he thus obtained nothing new, since, in accordance with the rule of the law, he was the undoubted successor of his father, I reply, that it is not un-common that what God had already freely promised, He declares that He will give by way of reward. Thus, what had been promised to Abraham before the birth of Isaac, is again repeated after he was prepared to sacrifice him, (Genesis 22:16:) "Because thou hast done this thing, and hast not withheld thy son," therefore, "in blessing I will bless thee, and in thy seed shall all the nations of the earth be blessed." Besides, the privilege of a single individual is not simply in question here, but it refers to a perpetual succession, as if God had promised that his posterity should never fail. And assuredly, the change which took place at the commencement of Solomon's reign, is not repugnant to this promise, for it may be probably inferred that Zadoc, no less than Abiathar, was of the race of Phinehas. This covenant is called a "covenant of peace," because it was to be surely established; consequently, it may be properly rendered, "My covenant in peace." At any rate, it indicates prosperity, as if He had said that Phinehas, together with his posterity, should prosperously execute the sacerdotal office.
1 - Margin, A.V., "Heb., with my zeal."
2 - Psalm 106:30 A.V., "Then stood up Phinehas, and executed judgment;" in the English Prayer-book, the Chaldee, Syriac, and other versions, "and prayed;" with this, however, C., in his Commentary, does not agree: "Some render the word phll, pillel, to pray, (he says;) but the other rendering, to execute justice, is more in accordance with the context." -- Cal. Sec. Edit., vol. 4, p. 230
And the Lord spake unto Moses,.... Out of the cloud, or out of the tabernacle, at the door of which Moses now was, Numbers 25:6, this was after so many had died of the plague, and after the fact of Phinehas, by which it was stopped: saying; as follows.
For this act of divine zeal the eternal possession of the priesthood was promised to Phinehas and his posterity as Jehovah's covenant of peace. בּקנאו, by displaying my zeal in the midst of them (viz., the Israelites). קנאתי is not "zeal for me," but "my zeal," the zeal of Jehovah with which Phinehas was filled, and impelled to put the daring sinners to death. By doing this he had averted destruction from the Israelites, and restrained the working of Jehovah's zeal, which had manifested itself in the plague. "I gave him my covenant of peace" (the suffix is attached to the governing noun, as in Leviticus 6:3). בּרית נתן, as in Genesis 17:2, to give, i.e., to fulfil the covenant, to grant what was promised in the covenant. The covenant granted to Phinehas consisted in the fact, that an "eternal priesthood" (i.e., the eternal possession of the priesthood) was secured to him, not for himself alone, but for his descendants also, as a covenant, i.e., in a covenant, or irrevocable form, since God never breaks a covenant that He has made. In accordance with this promise, the high-priesthood which passed from Eleazar to Phinehas (Judges 20:28) continued in his family, with the exception of a brief interruption in Eli's days (see at 1 Sam 1-3 and 1-Samuel 14:3), until the time of the last gradual dissolution of the Jewish state through the tyranny of Herod and his successors (see my Archologie, 38). - In Numbers 25:14, Numbers 25:15, the names of the two daring sinners are given. The father of Cozbi, the Midianitish princess, was named Zur, and is described here as "head of the tribes (אמּות, see at Genesis 25:16) of a father's house in Midian," i.e., as the head of several of the Midianitish tribes that were descended from one tribe-father; in Numbers 31:8, however, he is described as a king, and classed among the five kings of Midian who were slain by the Israelites.
