John 10:1-5

1 Truly I say to you, He who does not go through the door into the place where the sheep are kept, but gets in by some other way, is a thief and an outlaw.

2 He who goes in by the door is the keeper of the sheep.

3 The porter lets him in; and the sheep give ear to his voice; he says over the names of the sheep, and takes them out.

4 When he has got them all out, he goes before them, and the sheep go after him, for they have knowledge of his voice.

5 They will not go after another who is not their keeper, but will go from him in flight, because his voice is strange to them.
