King James wording
King James Version
I speak not of you all: I know whom I have chosen: but that the scripture may be fulfilled, He that eateth bread with me hath lifted up his heel against me.THE KEY
The heel raised after shared bread turns betrayal into a physical reversal of fellowship: the table’s closeness becomes the place from which the wound comes.
THE MEANING
Jesus knows the person he chooses, even when that person turns against him. You can find the verse speaking where closeness and harm occupy the same table: shared bread does not guarantee shared loyalty. The wound is intimate, and it is seen clearly.
WHAT THIS UNDOES
It undoes the belief that closeness or being chosen makes betrayal impossible: the one nearest the table can still raise a heel against the one who shares it.
THE ROOT
πτέρναν
pternan
GROWS FROM
πτερν
ptern
Heel; the word family also carries the sense of tripping or supplanting.
The Greek noun names the heel, while its related verb means to trip or supplant, as in the Greek text of Genesis 27:36. Behind John’s quotation, the Hebrew Psalm uses עָקֵב (aqeb, “heel”), echoing יַעֲקֹב (Ya’aqov, “Jacob”) and עָקַב (aqav, “to supplant”): the heel gathers betrayal and displacement into one image.
ALSO GROWS
pterna: Heel.
πτέρνα
This is the noun behind the raised heel; a body part becomes the image of an intimate turn against someone.
pternizō: Trip, supplant.
πτερνίζω
The Greek text uses this related verb for Jacob’s supplanting in Genesis 27:36, linking the heel with displacement.
ἐξελεξάμην
exelexamēn
GROWS FROM
λεγ
leg
The selecting or picking-out sense carried by this verb family.
The word for choosing describes selection from among others, which sharpens the force of “not of you all.” Jesus’ knowing is specific: the verse holds the chosen person’s identity clearly in view even as betrayal unfolds.
ALSO GROWS
eklegomai: Choose, select.
ἐκλέγομαι
This is the verb used for “I have chosen,” making selection the center of the clause.
eklogē: Choice, selection.
ἐκλογή
The related noun makes explicit the act of choosing that the verse pairs with knowing.
eklektos: Chosen, selected.
ἐκλεκτός
This adjective names one who has been picked out, reinforcing the particularity of the choice.
πληρωθῇ
plērōthē
GROWS FROM
πληρ
plēr
Full, filled up.
“filled” in this verse is plērōthē. The language of fulfillment carries the image of something brought to fullness, not merely a prediction checked off. The verse presents the betrayal as a pattern now taking shape in lived action.
ALSO GROWS
plēroō: Fill, make full; fulfill.
πληρόω
This verb family gives “fulfilled” its sense of bringing something to its full measure.
plērōma: Fullness, that which fills.
πλήρωμα
The noun shows the same root as fullness, adding depth to the idea of scripture coming to completion.
plērēs: Full, complete.
πλήρης
This related word makes the root’s sense of fullness visible in a completed state.
THE PATTERN
Betrayal can rise from intimacy; shared bread does not prevent the heel from turning against the one beside you.
Even the man of my wholeness, upon whom I leaned my weight, eats my bread and lifts his heel against me.And he said, Is he not rightly named Jacob, the heel-grasper? For he has grasped my heel these two times. He took away my birthright, and look, now he has taken away my blessing. And he said, Have you not kept back a blessing for me?But look, the hand of the one handing me over is with me on the table.THE THREAD
Even the man of my wholeness, upon whom I leaned my weight, eats my bread and lifts his heel against me.John’s line carries this Psalm’s heel image into the scene of shared bread. The Hebrew עָקֵב (aqeb, “heel”) also echoes יַעֲקֹב (Ya’aqov, “Jacob”) and עָקַב (aqav, “to supplant”), joining the raised heel to betrayal from within a close bond.
