John 17:6-12 New American Standard Bible (NASB)
6 “I have manifested Your name to the men whom You gave Me out of the world; they were Yours and You gave them to Me, and they have kept Your word. 7 Now they have come to know that everything You have given Me is from You; 8 for the words which You gave Me I have given to them; and they received them and truly understood that I came forth from You, and they believed that You sent Me. 9 I ask on their behalf; I do not ask on behalf of the world, but of those whom You have given Me; for they are Yours; 10 and all things that are Mine are Yours, and Yours are Mine; and I have been glorified in them. 11 I am no longer in the world; and yet they themselves are in the world, and I come to You. Holy Father, keep them in Your name, the name which You have given Me, that they may be one even as We are. 12 While I was with them, I was keeping them in Your name which You have given Me; and I guarded them and not one of them perished but the a]son of perdition, so that the Scripture would be fulfilled.
