KJV: And when Jesus knew it, he saith unto them, Why reason ye, because ye have no bread? perceive ye not yet, neither understand? have ye your heart yet hardened?
NASB: And Jesus, aware of this, said to them, "Why do you discuss the fact that you have no bread? Do you not yet see or understand? Do you have a hardened heart?
KJV: 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.
NASB: "HE HAS BLINDED THEIR EYES AND HE HARDENED THEIR HEART, SO THAT THEY WOULD NOT SEE WITH THEIR EYES AND PERCEIVE WITH THEIR HEART, AND BE CONVERTED AND I HEAL THEM."
KJV: But their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ.
NASB: But their minds were hardened; for until this very day at the reading of the old covenant the same veil remains unlifted, because it is removed in Christ.
