'Perceive' in the Bible

And he says to them, Are ye also thus unintelligent? Do ye not perceive that all that is outside entering into the man cannot defile him,

And Jesus knowing it, says to them, Why reason ye because ye have no bread? Do ye not yet perceive nor understand? Have ye your heart yet hardened?

But they understood not this saying, and it was hid from them that they should not perceive it. And they feared to ask him concerning this saying.

And Peter opening his mouth said, Of a truth I perceive that God is no respecter of persons,

saying, Men, I perceive that the navigation will be with disaster and much loss, not only of the cargo and the ship, but also of our lives.

saying, Go to this people, and say, Hearing ye shall hear and not understand, and seeing ye shall see and not perceive.
