English: “And it shall be accepted for him” – does leaning itself atone? Atonement comes only through the blood. Rather the verse teaches that if one treated the leaning as a residual mitzvah, Scripture still regards it as though atonement was achieved; from here we learn that s’michah is not indispensable.
Clarification of the relative weight of the mitzvah of semichah — it is required yet does not invalidate the offering if omitted under certain conditions.
While the leaning of hands is an important expression of identification with the offering, the essential atonement is effected by the blood service. The Torah still values the personal act of s’michah highly.
