'Understand' in the Bible

Therefore I speak to them in parables; because while seeing they do not see, and while hearing they do not hear, nor do they understand.

In their case the prophecy of Isaiah is being fulfilled, which says,‘You will keep on hearing, but will not understand;You will keep on seeing, but will not perceive;

For the heart of this people has become dull,With their ears they scarcely hear,And they have closed their eyes,Otherwise they would see with their eyes,Hear with their ears,And understand with their heart and return,And I would heal them.’

When anyone hears the word of the kingdom and does not understand it, the evil one comes and snatches away what has been sown in his heart. This is the one on whom seed was sown beside the road.

After Jesus called the crowd to Him, He said to them, “Hear and understand.

Do you not understand that everything that goes into the mouth passes into the stomach, and is eliminated?

Do you not yet understand or remember the five loaves of the five thousand, and how many baskets full you picked up?

How is it that you do not understand that I did not speak to you concerning bread? But beware of the leaven of the Pharisees and Sadducees.”

“Therefore when you see the abomination of desolation which was spoken of through Daniel the prophet, standing in the holy place (let the reader understand),

and they did not understand until the flood came and took them all away; so will the coming of the Son of Man be.
