Bearing in mind that the Pasuk in Shemos (29:21) mentions the sprinkling of the Shemen ha'Mishchah and the blood before Haktarah of the Eimurim and Shok of Eil ha'Milu'im, why did Moshe sprinkle after Haktarah?
Ramban, Moshav Zekenim: Moshe learned from the end of that Pasuk "v'Kadash 1 Hu u'Vanav ... ", that these sprinklings 2 finalized the Kedushah of Aharon and his sons 3 , as the Pasuk goes on to state here.
Were the oil and the blood mixed (as were the bloods of the bull and the goat or not) or were they sprinkled separately?
Ramban: The question remains unanswered, since there is no indication either way.
Seeing as the Pasuk here indicates that the Kedushah of Aharon and his sons was finalized via these sprinklings and not via the anointing (as we just explained), why, in Pasuk 12, did the Torah write "Vayimshach oso Lekadsho"?
Ramban: Because the Kedushah process began there and ended here.
