John 10:2-5

²but the person who goes in through the door is shepherd to the sheep.

³For him the watchman opens the door; and the sheep listen to his voice; and he calls his own sheep by name, and leads them out.

⁴When he has brought them all out, he walks in front of them, and his sheep follow him, because they know his voice.

⁵They will not follow a stranger, but will run away from him; because they do not know a stranger's voice.”
