John 17:11-12

And I am no more in the world, and these are in the world, and I come to thee. Holy Father, keep them in thy name which thou hast given me, that they may be one, even as we are. While I was with them, I kept them in thy name which thou hast given me: and I guarded them, and not one of them perished, but the son of perdition; that the scripture might be fulfilled.
