English: “For a wave offering to atone” — does a wave offering atone? Atonement is only through blood! Rather, if he performed the tenufah as a remnant of the mitzvah, Scripture credits him as though he had not atoned and [yet] had atoned.
Status of the tenufah
Chazal clarify that the tenufah itself does not effect kapparah; the blood does. Nevertheless the tenufah remains a required element of the procedure.
