But he that is an hireling, and not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and fleeth: and the wolf catcheth them, and scattereth the sheep.

To him the porter openeth; and the sheep hear his voice: and he calleth his own sheep by name, and leadeth them out.

And when he putteth forth his own sheep, he goeth before them, and the sheep follow him: for they know his voice.
