'Understand' in the Bible

He thought his own people would understand that God was delivering them through him, but they did not understand.

So Philip ran up to it and heard the man reading Isaiah the prophet. He asked him, "Do you understand what you're reading?"

Then Peter started speaking: "I now truly understand that God does not show favoritism in dealing with people,

Those who were with me saw the light, but did not understand the voice of the one who was speaking to me.

when he said, 'Go to this people and say, "You will keep on hearing, but will never understand, and you will keep on looking, but will never perceive.

For the heart of this people has become dull, and their ears are hard of hearing, and they have closed their eyes, so that they would not see with their eyes and hear with their ears and understand with their heart and turn, and I would heal them."'
