Side-ring EXTRA · Mutual dependence of the two seirim
Torah Temimah indexes equality material primarily on 16:05. On 16:07 the classical sources emphasize that the two goats function as a single paired unit from the moment they are stood before Hashem.
English: The two Yom Kippur goats are interdependent — each holds back the validity of the other until both are present and designated.
Me’akev (pair interdependence)
From the moment of “he shall take the two seirim and stand them,” neither goat can complete its role without the other. The goral, the chatas, and the dispatch all presuppose an intact pair.
