English: “And the sons of Aharon shall bring near” — the sons of Aharon and not the daughters of Aharon; from here, receiving the blood applies to men and not to women.
In the sugya: Parallel to semicha’s “Bnei Yisrael,” “Bnei Aharon” selects male Kohanim for kabbalah. Daughters of Aharon are outside this formal receiving of the blood.
Type of Learning
Miyut from “Bnei Aharon” — kabbalah is male-Kohen avodah.
What Is Learned
Kabbalah of the blood is a male-Kohen avodah; women are excluded from this formal receiving. “Sons of Aharon” is the textual hinge for that limit.
