John 13:21
“When Jesus had thus said, he was troubled in spirit, and testified, and said, Verily, verily, I say unto you, that one of you shall betray me.”
King James Version
Troubled in spirit at the Last Supper, Jesus testifies plainly: 'one of you shall betray me' — having just cited Psalm 41:9, 'he that eateth bread with me hath lifted up his heel against me' (Jn. 13:18). Judas leaves and the word is fulfilled that night.

How Traditions Read This Prophecy
Apostolic (Oneness) PentecostalJesus announces the betrayal 'that ye may believe that I am he' (Jn. 13:19) — ego eimi. Days later the same spectrum flashes at the arrest: they seek 'Jesus of Nazareth,' the most human of titles, He answers 'I AM,' and soldiers fall to the ground (Jn. 18:5-8). The Prophet bears the divine name.
JewishPsalm 41 is David's complaint about a treacherous friend (often linked to Ahithophel); it is a lament, not a messianic prediction.
CatholicThe Lord's foreknowledge of Judas fulfills the Scripture and shows the Passion was embraced, not suffered unawares.
ProtestantThe Ahithophel-David pattern (2 Sam. 15-17) becomes typology: the greater David is betrayed by the intimate table-companion.
DispensationalOne of several precise same-week predictions establishing Jesus' prophetic credentials at the Passion.
AcademicJohn 13:18-21 explicitly frames the betrayal as fulfillment of Psalm 41:9; the ego eimi formula in v.19 deliberately echoes Isaiah 43:10 LXX.
