Who Was The Good Shepherd?

Jesus said that he was the Good Shepherd and would die for his people:

11 I am the good shepherd. The good shepherd would die so that he can save his sheep. 12 Another man may take care of sheep so that he gets money. But the sheep do not belong to him. A man like that is not the shepherd. If a wolf comes, a man like that runs away when he sees it. He leaves the sheep in danger. Then the wolf attacks the sheep. It causes them to run away in all directions. 13 That man runs away because the sheep do not belong to him. He does not think that the sheep are important.

14 I am the good shepherd. I know my own sheep, and they know me. 15 I know them in the same way that my Father knows me. And they know me in the same way that I know the Father. I will die so that I can save my sheep. 16 I also have other sheep, and I must bring them too. They do not belong to this group of sheep. But they also will listen to my voice. So all the sheep will become one group, and they will have one shepherd. 17 The Father loves me because I choose to die for my sheep. But after I give my life like that, I will become alive again. 18 Nobody can take my life away from me. Instead, I myself can choose to die. I have authority to do that. I also have authority to become alive again. My Father has said that I must do that.’
