'Shepherd' in the Bible

But one who enters in by the door is the shepherd of the sheep.

I am the good shepherd. The good shepherd lays down his life for the sheep.

He who is a hired hand, and not a shepherd, who doesn't own the sheep, sees the wolf coming, leaves the sheep, and flees. The wolf snatches the sheep, and scatters them.

I am the good shepherd. I know my own, and I'm known by my own;

I have other sheep, which are not of this fold. I must bring them also, and they will hear my voice. They will become one flock with one shepherd.
