யோவான் 10:3-5
3
To him the porter openeth; and the sheep hear his voice: and he calleth his own sheep by name, and leadeth them out.
4
And when he putteth forth his own sheep, he goeth before them, and the sheep follow him: for they know his voice.
5
And a stranger will they not follow, but will flee from him: for they know not the voice of strangers.
