• Matthew 13:15
  For the hearts of this people have grown dull.
  Their ears are hard of hearing,
  And their eyes they have closed,
  Lest they should see with their eyes and hear with their ears,
  Lest they should understand with their hearts and turn,
  So that I should heal them."
   
• Isaiah 6:10
  ' Make the heart of this people dull,
  And their ears heavy,
  And shut their eyes;
  Lest they see with their eyes,
  And hear with their ears,
  And understand with their heart,
  And return and be healed.'

• Romans 10:1-3
  Brethren, my heart's desire and prayer to God for Israel is that they may be saved. For I bear them witness that they have a zeal for God, but not according to knowledge. For they being ignorant of God's righteousness, and seeking to establish their own righteousness, have not submitted to the righteousness of God.
