Psalms 79:13

So we thy people and sheep of thy pasture will give thee thanks for ever: we will shew forth thy praise to all generations.

God's people belong to Him as sheep belong to the pasture that sustains them. The verse presents them in prayer as a flock that must be fed and watched over. That feeding and watchcare calls for a tender, constant oversight. No human leader is equal to providing it by his own strength.
