Deuteronomy 29:4

4But to this day athe Lord has not given you a heart to understand or eyes to see or ears to hear.

Isaiah 6:9-10

9And he said, “Go, and say to this people:

b“‘Keep on hearing,
Or Hear indeed
but do not understand;
keep on seeing,
Or see indeed
but do not perceive.’
10 eMake the heart of this people fdull,
Hebrew fat

and their ears heavy,
and blind their eyes;
hlest they see with their eyes,
and hear with their ears,
and understand with their hearts,
and turn and be healed.”

Isaiah 44:18

18They know not, nor do they discern, for he has shut their eyes, so that they cannot see, and their hearts, so that they cannot understand.

Jeremiah 5:21

21Hear this, iO foolish and senseless people,
jwho have eyes, but see not,
who have ears, but hear not.

Matthew 13:14-15

14Indeed, in their case the prophecy of Isaiah is fulfilled that says:

k“‘“You will indeed hear but never understand,
and you will indeed see but never perceive.”
15For this people’s heart has grown dull,
and with their ears lthey can barely hear,
and mtheir eyes they have closed,
lest they should see with their eyes
and hear with their ears
and nunderstand with their heart
and oturn, and I would heal them.’

Luke 8:10

10he said, p“To you it has been given to know qthe secrets of the kingdom of God, but for others they are in parables, so rthatseeing they may not see, and hearing they may not understand.’
