פּירוש אויף במדבר 25:13

“Thus making expiation for the Israelites” [25:13]. He atoned for Israel. From here we learn that the one who kills evildoers, it is as if he brought a sacrifice.⁵Bahya, Numbers, 25:13.

והיתה לו AND IT SHALL BE UNTO HIM — this covenant of Mine shall be unto him —

And it shall be to him and his descendants after him an everlasting covenant of priesthood. These are the twenty-four priestly gifts, in return for his zeal (Isaiah 33:12), "In return for his fervor, he made atonement for his people." It is not only said "made atonement," but "made atonement for the children of Israel." "Made atonement" is mentioned until now, indicating that it continues to atone even for the deceased.
