Numbers 25:18
For they assailed you deceitfully when they seduced you in the matter of Peor and their sister Cozbi, the daughter of the Midianite leader, the woman who was killed on the day the plague came because of Peor."
For they assailed you deceitfully

Midian and Moab did not prevail through open warfare but through a calculated spiritual attack. Their scheme exploited Israel’s vulnerability to idolatry and sexual immorality, drawing the people away from covenant faithfulness to the LORD. Balaam had counseled this strategy, as Numbers 31:16 later confirms. The danger of deceit runs throughout Scripture, from the serpent’s seduction of Eve in Genesis 3 to the false teachings that threaten the church. God’s people must remain watchful because rebellion often begins with an invitation that appears desirable or harmless.

when they seduced you in the matter of Peor

At Baal Peor, Israel joined itself to Moabite worship through sacrificial meals and immorality with foreign women (Numbers 25:1–3). The sin was not merely personal misconduct; it was covenant betrayal, for Israel gave honor to a false god rather than to the LORD who had redeemed them. The judgment that followed revealed the deadly seriousness of idolatry. Friendship with the world’s rebellious values remains spiritual adultery against God (James 4:4).

Deu 4:3-4 Your eyes have seen what the LORD did at Baal-peor…
Hos 9:10 I found Israel like grapes in the wilderness…
Jos 22:17 Was not the sin of Peor enough for us…

and their sister Cozbi, the daughter of the Midianite leader,

Cozbi was the daughter of Zur, a Midianite tribal leader, and her prominence shows that the seduction of Israel involved more than isolated acts. Midianite leadership participated in a deliberate attempt to corrupt the nation God had chosen. Her public union with Zimri, a leader from the tribe of Simeon, displayed open contempt for God’s holiness while Israel mourned at the entrance to the tent of meeting.

the woman who was killed on the day the plague came because of Peor.”

Phinehas killed Cozbi and Zimri, and the plague stopped after twenty-four thousand Israelites had died (Numbers 25:6–9, 14–15). Their deaths demonstrated God’s righteous judgment upon those who led His people into sin and those who willingly embraced it. The severity of Peor points to the penalty sin deserves, a penalty ultimately borne by Christ for all who repent and believe in Him.

Whether Vengeance is Lawful?
Objection 1: It seems that vengeance is not lawful. For whoever usurps what is God's sins. But vengeance belongs to God, for it is written (Dt. 32:35, Rom. 12:19): "Revenge to Me, and I will repay." Therefore all vengeance is unlawful. Objection 2: Further, he that takes vengeance on a man does not bear with him. But we ought to bear with the wicked, for a gloss on Cant 2:2, "As the lily among the thorns," says: "He is not a good man that cannot bear with a wicked one." Therefore we should not take

The Covenant of an Everlasting Priesthood
"That My covenant might be with Levi. My covenant was with him of life and peace; and I gave them to him for the fear wherewith he feared Me, and was afraid before My name. The law of truth was in his mouth, and iniquity was not found in his lips; he walked with Me in peace and equity, and did turn many away from iniquity."--MAL. ii. 4-6. ISRAEL was meant by God to be a nation of priests. In the first making of the Covenant this was distinctly stipulated. "If ye will obey My voice, and keep My covenant,

How those that are at Variance and those that are at Peace are to be Admonished.
(Admonition 23.) Differently to be admonished are those that are at variance and those that are at peace. For those that are at variance are to be admonished to know most certainly that, in whatever virtues they may abound, they can by no means become spiritual if they neglect becoming united to their neighbours by concord. For it is written, But the fruit of the Spirit is love, joy, peace (Gal. v. 22). He then that has no care to keep peace refuses to bear the fruit of the Spirit. Hence Paul

Numbers
Like the last part of Exodus, and the whole of Leviticus, the first part of Numbers, i.-x. 28--so called,[1] rather inappropriately, from the census in i., iii., (iv.), xxvi.--is unmistakably priestly in its interests and language. Beginning with a census of the men of war (i.) and the order of the camp (ii.), it devotes specific attention to the Levites, their numbers and duties (iii., iv.). Then follow laws for the exclusion of the unclean, v. 1-4, for determining the manner and amount of restitution
