Jn 10:11-18
At that time, Jesus said: I am the good shepherd. The good shepherd lays down his life for the sheep. He who is a hireling and not a shepherd, whose own the sheep are not, sees the wolf coming and leaves the sheep and flees; and the wolf snatches them and scatters them. He flees because he is a hireling and cares nothing for the sheep. I am the good shepherd; I know my own and my own know me, as the Father knows me and I know the Father; and I lay down my life for the sheep.
