At the beginning of this parsha

Additionally, having come into direct contact with death through the execution of Zimri and Cozbi, he might be disqualified from Divine service in the Tabernacle. As a result, it was publicized to the entire congregation that
After mentioning his rewards of the covenant of peace and the covenant of the priesthood, the Torah specifically mentions the names and importance of the two transgressors, to teach us the magnitude of Pinchas’ act. Again, the covenant of peace would be with the blood avengers of Zimri’s tribe, from whom Pinchas would be Divinely protected.
However, there would be no covenant of peace with the Midianites. They were to be totally destroyed. The actual command to go to war with Midianites is given later in Parshat Mattot-Masei. Here the Torah is letting us know the extent of the enmity between Bnei Yisrael and Midian, which is the reason for the total destruction to follow. The Torah tells us that the Midianites harassed Bnei Yisrael with their conspiracies. That is to say, they maliciously conspired to destroy us through the matter of Ba’al Peor, the attempt to curse us through Bilaam and the brazen immorality of Cozbi, the daughter of one of Midian’s most important leaders.
