John 17:12

10 All I have is Yours, and all You have is Mine; and in them I have been glorified.

11 I will no longer be in the world, but they are in the world, and I am coming to You. Holy Father, protect them by Your name, the name You gave Me, so that they may be one as We are one.

While I was with them, I protected and preserved them by Your name, the name You gave Me. Not one of them has been lost, except the son of destruction, so that the Scripture would be fulfilled.

13 But now I am coming to You; and I am saying these things while I am in the world, so that they may have My joy fulfilled within them.

14 I have given them Your word and the world has hated them; for they are not of the world, just as I am not of the world.

Do read the surrounding verses too, because the context often says more than a single verse.
