'Perceive' in the Bible

And they were not knowing this saying, and it was veiled from them, that they might not perceive it, and they were afraid to ask him about this saying.

And having turned unto the disciples, he said, by themselves, 'Happy the eyes that are perceiving what ye perceive;

for I say to you, that many prophets and kings did wish to see what ye perceive, and did not see, and to hear what ye hear, and did not hear.'
