English: “And the kohen shall atone for him from his chatas” — that the kapparah be for the sake of a chatas; from here we require zerikah lishmah.
Zerikah must be for the sake of chatas — blood application of the nasi’s offering must be done with chatas intent.
The zerikah (or netinat dam) of the nasi’s chatas must be performed with the specific intent that it is a chatas. Application done with intent for a different offering-type fails the requirement derived from “me-chatato.”
