'Shepherd' in the Bible

But he that entereth in by the door is the shepherd of the sheep.

I am the good shepherd: the good shepherd layeth down his life for the sheep.

He that is a hireling, and not a shepherd, whose own the sheep are not, beholdeth the wolf coming, and leaveth the sheep, and fleeth, and the wolf snatcheth them, and scattereth them :

I am the good shepherd; and I know mine own, and mine own know me,

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