John 10:2-5

2but he that enters in by the door is [the] shepherd of the sheep.

3To him the porter opens; and the sheep hear his voice; and he calls his own sheep by name, and leads them out.

4When he has put forth all his own, he goes before them, and the sheep follow him, because they know his voice.

5But they will not follow a stranger, but will flee from him, because they know not the voice of strangers.
