'Shepherd' in the Bible

The one who enters by the door is the shepherd of the sheep.

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

The hired hand, who is not a shepherd and does not own sheep, sees the wolf coming and abandons the sheep and runs away. So the wolf attacks the sheep and scatters them.

"I am the good shepherd. I know my own and my own know me --

I have other sheep that do not come from this sheepfold. I must bring them too, and they will listen to my voice, so that there will be one flock and one shepherd.

Jesus said a second time, "Simon, son of John, do you love me?" He replied, "Yes, Lord, you know I love you." Jesus told him, "Shepherd my sheep."
