What does John 17:7 mean?

I glorified you on the earth. I have accomplished the work which you have given me to do.

Now, Father, glorify me with your own self with the glory which I had with you before the world existed.

I revealed your name to the people whom you have given me out of the world. They were yours, and you have given them to me. They have kept your word.

for the words which you have given me I have given to them, and they received them, and knew for sure that I came from you, and they have believed that you sent me.

I pray for them. I don’t pray for the world, but for those whom you have given me, for they are yours.

All things that are mine are yours, and yours are mine, and I am glorified in them.
