To date  P52 is the oldest extant verse discovered from the New Testament at approximately 125 AD. I find it interesting that almost the whole of the Gospel is stated in these words from this tiny fragment.

From Wikipedia, the free encyclopedia

The papyrus is written on both sides and hence must be from a codex, a sewn and folded book, not a scroll, roll or isolated sheet; and the surviving portion also includes part of the top and inner margins of the page. The recto consequently preserves the top left corner of a right-hand page; while the verso preserves the top right corner of a left-hand page. The characters in bold style are the ones that can be seen in Papyrus ⁵².

Gospel of John 18:31-33 (recto)

ΟΙ ΙΟΥΔΑΙΟΙ ΗΜΕIΝ ΟΥΚ ΕΞΕΣΤΙΝ ΑΠΟΚΤΕΙΝΑΙ

ΘΝHΣΚΕΙΝ ΙΣΗΛΘΕΝ ΟΥΝ ΠΑΛΙΝ ΕΙΣ ΤΟ ΠΡΑΙΤΩ-
ΡΙΟΝ Ο ΠIΛΑΤΟΣ ΚΑΙ ΕΦΩΝΗΣΕΝ ΤΟΝ ΙΗΣΟΥΝ

…

the Jews, “For us it is not permitted to kill
anyone,” so that the word of Jesus might be fulfilled, which he sp-
oke signifying what kind of death he was going to
die. Entered therefore again into the Praeto-
rium Pilate and summoned Jesus
and said to him, “Thou art king of the
Jews?”

Gospel of John 18:37-38 (verso)

ΒΑΣΙΛΕΥΣ ΕΙΜΙ ΕΓΩ ΕΙΣ TOΥΤΟ ΓΕΓΕΝΝΗΜΑΙ

ΡΗΣΩ ΤΗ ΑΛΗΘΕΙΑ ΠΑΣ Ο ΩΝ EΚ ΤΗΣ ΑΛΗΘΕI-
ΑΣ ΑΚΟΥΕΙ ΜΟΥ ΤΗΣ ΦΩΝΗΣ ΛΕΓΕΙ ΑΥΤΩ
Ο ΠΙΛΑΤΟΣ ΤΙ ΕΣΤΙΝ ΑΛΗΘΕΙΑ ΚAΙ ΤΟΥΤO
ΕΙΠΩΝ ΠΑΛΙΝ ΕΞΗΛΘΕΝ ΠΡΟΣ ΤΟΥΣ ΙΟΥ-
ΔΑΙΟΥΣ ΚΑΙ ΛΕΓΕΙ ΑΥΤΟΙΣ ΕΓΩ ΟΥΔEΜΙΑΝ
ΕΥΡΙΣΚΩ ΕΝ ΑΥΤΩ ΑΙΤΙΑΝ

…

a King I am. For this I have been born
and (for this) I have come into the world so that I would test-
ify to the truth. Everyone who is of the truth
hears of me my voice.” Said to him
Pilate, “What is truth?” and this
having said, again he went out unto the Jews
and said to them, “I find not one
fault in him.”
