John 10:2-5
10:2 The one who enters by the door is the shepherd of the sheep.
10:3 The doorkeeper opens the door for him, and the sheep hear his voice. He calls his own sheep by name and leads them out.
10:4 When he has brought all his own sheep out, he goes ahead of them, and the sheep follow him because they recognize his voice.
10:5 They will never follow a stranger, but will run away from him, because they do not recognize the stranger’s voice.”
