'Perceive' in the Bible

But when you are giving in charity, let not your left hand perceive what your right hand is doing,

He who has ears to hear, let him hear and heed My words.

He who has ears [to hear], let him hear and heed My words.”

And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive:

For this people's heart is waxed gross, And their ears are dull of hearing, And their eyes they have closed; Lest haply they should perceive with their eyes, And hear with their ears, And understand with their heart, And should turn again, And I should heal them.

Then the righteous [those who seek the will of God] will shine forth [radiating the new life] like the sun in the kingdom of their Father. He who has ears [to hear], let him hear and heed My words.

Perceive ye not, that whatsoever goeth into the mouth passeth into the belly, and is cast out into the draught?

Do ye not yet perceive, neither remember the five loaves of the five thousand, and how many baskets ye took up?

How is it that ye do not perceive that I spake not to you concerning bread? But beware of the leaven of the Pharisees and Sadducees.
