English: “On the head of the goat” — why say “the goat”? To include Nachshon’s goat for semichah.
Ribbuy of tribal-prince goats for semichah — even a tribal nasi’s chatas goat requires semichah.
The verse’s wording includes the goats offered by the nesi’im of the tribes. Semichah is therefore required not only for the ordinary individual’s chatas and the king’s goat, but also for the special chatas of a tribal prince. The ribbuy prevents any exclusion of those offerings from the leaning requirement.
