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

Psalms 69:23

23 bLet their eyes be darkened, so that they cannot see,
cand make their loins tremble continually.

Psalms 115:5-8

5They have mouths, dbut do not speak;
eyes, but do not see.
6They have ears, but do not hear;
noses, but do not smell.
7They have hands, but do not feel;
feet, but do not walk;
and they do not make a sound in their throat.
8 eThose who make them become like them;
so do all who trust in them.

Isaiah 6:9-10

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

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

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

Isaiah 42:18-20

Israel’s Failure to Hear and See

18 Hear, you deaf,
and look, you blind, that you may see!
19Who is blind but my servant,
or deaf as my messenger whom I send?
Who is blind as my dedicated one,
Or  as the one at peace with me

or blind as the servant of the Lord?
20 nHe sees many things, but does not observe them;
ohis ears are open, but he does not hear.

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.

Mark 4:12

12 pso that

“'they qmay indeed see but not perceive,
and may indeed hear but not understand,
lest they rshould turn and be forgiven.'”
