The prophetic word to David had been he would be a shepherd of the people of God (he would feed them or keep them) and he would be their prince (ruler or leader).
These two expressions really do define the twin responsibilities found in leadership in the Kingdom of God.
If you are a spiritual leader then you are called to shepherd or feed and protect the people. The welfare of the people must be your concern.
Spiritual shepherds must also understand they are to lead the people of God. While dictatorship is not to be practiced ruler-ship cannot be abdicated.
Others would be a part of the leadership team but the final responsibility for the team rested with David.
