John 10:15

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.

The hired hand flees because he is a hired hand and doesn’t care for the sheep.

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.

Therefore the Father loves me, because I lay down my life, that I may take it again.

No one takes it away from me, but I lay it down by myself. I have power to lay it down, and I have power to take it again. I received this commandment from my Father.”
