King James wording
King James Version
He hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them.THE KEY
The verse places healing at the end of a path that God’s blinding and the heart’s callousness close before the turn can happen.
THE MEANING
This verse confronts you now with a severe claim: God blinds eyes and hardens hearts, so people do not see, understand, turn, or receive healing. It binds perception, understanding, turning, and healing into one sequence, with the calloused heart blocking the way through it.
WHAT THIS UNDOES
It unsettles the belief that healing can bypass perception and turning; here, healing follows a turn the hardened heart does not make.
THE ROOT
πεπώρωκεν
peporōken
GROWS FROM
πωρ-
pōr-
The stem carries the sense of a callus or hard growth; πωρόω (pōroō) means to make callous or hard.
“hardened” in this verse is peporōken. The Greek word pictures more than a stubborn choice: it evokes a callus that makes a surface insensible. That callousness is paired here with blinded eyes, making both outer sight and inward perception unresponsive.
ALSO GROWS
pōros: Callus or hard stone
πῶρος
The hard, insensitive image gives “hardened” a physical edge: the heart is described as covered over.
pōrōsis: Hardness or callousness
πώρωσις
This related form names the same kind of dulled condition that obstructs perception in the verse.
στραφῶσιν
straphōsin
GROWS FROM
στρεφ-
streph-
Turn or turn around.
“turned” in this verse is straphōsin. στραφῶσιν (straphōsin, “they turn”) names a change of direction, not merely a change of opinion. The verse places that turn between understanding and healing: the calloused heart closes the turn, and with it the way to restoration.
ALSO GROWS
strephō: Turn
στρέφω
The basic verb makes the verse’s “converted” concrete as a turning.
epistrephō: Turn back or return
ἐπιστρέφω
This related form shows how turning can mean a return of direction, the movement the verse says is blocked.
ἰάσομαι
iasomai
GROWS FROM
ἰα-
ia-
Heal, cure, restore.
The Greek ἰάσομαι (iasomai, “I will heal”) names the restoration at the end of the blocked sequence. The Isaiah line behind this saying uses וְרָפָא (wə-rāfāʾ, “and be healed”); its echo with רָפָה (rāfāh, “release, let the hands drop”) lets healing appear as what follows when closure releases.
ALSO GROWS
iasis: Healing or cure
ἴασις
This related noun names healing as an event of restoration, the outcome withheld when the turn is blocked.
iatros: Physician or healer
ἰατρός
The related word for a healer keeps the verse’s focus on restoration as a real act, not merely a change in understanding.
THE PATTERN
When perception is shut and the heart is insensible, the path from understanding through turning to healing is blocked.
Make the heart of this people fat, make their ears heavy, and smear over their eyes, lest they see with their eyes, and hear with their ears, and discern with their heart, and turn back, and be healed.Yet the LORD has not given you a heart to perceive, and eyes to see, and ears to hear and respond, to this day.For they did not put the loaves together, for their heart had turned to stone.THE THREAD
Make the heart of this people fat, make their ears heavy, and smear over their eyes, lest they see with their eyes, and hear with their ears, and discern with their heart, and turn back, and be healed.Isaiah gives the sequence that John compresses: perception, understanding, turning, then healing. The echo makes the severity of the present verse plain: the closure reaches all the way to the turn that healing would follow.
