The point of the Servant sections of Isaiah is precisely that both Israel and an individual are needed, the individual to spur Israel to carry out her mission, Israel to be spurred.
Hermisson says: “The prophetic office is inseparably bound up with the office of that other Servant, Israel. The first servant text and the beginning and end of the second describe a effect that only both Servants working together can achieve. But the specific office holder of the Servant Songs is the prophet, the last prophet . . . to whom this office is entrusted.
