'Shepherd' in the Bible

But the one who enters through 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 the shepherd, whose own the sheep are not, sees the wolf approaching and abandons the sheep and runs away--and the wolf seizes them and scatters [them]--

"I am the good shepherd, and I know my [own], and my [own] know me,

And I have other sheep which are not from this fold. I must bring these also, and they will hear my voice, and they will become one flock--one shepherd.

He said to him again a second time, "Simon [son] of John, do you love me?" He said to him, "Yes, Lord, you know that I love you." He said to him, "Shepherd my sheep!"
