3 The gatekeeper opens the gate for him, and the sheep listen to his voice. He calls his own sheep by name and leads them out. 4 When he has brought out all his own, he goes on ahead of them, and his sheep follow him because they know his voice. 5 But they will never follow a stranger; in fact, they will run away from him because they do not recognize a stranger's voice." 6 Jesus used this figure of speech, but the Pharisees did not understand what he was telling them.
