John 12:39 WBT

³⁷  But though he had done so many miracles before them, yet they believed not on him:

³⁸  That the saying of Isaiah the prophet might be fulfilled, which he spoke, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed?

³⁹  Therefore they could not believe, because that Isaiah said again,

⁴⁰  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.

⁴¹  These things said Isaiah, when he saw his glory, and spoke of him.
