English: It was taught: Might this mean a tribal nasi? The verse says “of all the commandments of Hashem his God,” and of a king it says “so that he may learn to fear….”
Nasi = king of all Israel — the nasi of this chapter is the king over all Israel, not a tribal chief.
The special chatas of the nasi is limited to the king who rules over the entire nation. A tribal nasi or local leader does not bring this offering. The linguistic parallel to the king’s Torah in Deuteronomy supplies the restriction.
