'Understand' in the Bible

The king said to them, “I had a dream and my spirit is anxious to understand the dream.”

But as for me, this mystery has not been revealed to me for any wisdom residing in me more than in any other living man, but for the purpose of making the interpretation known to the king, and that you may understand the thoughts of your mind.

When I, Daniel, had seen the vision, I sought to understand it; and behold, standing before me was one who looked like a man.

So he came near to where I was standing, and when he came I was frightened and fell on my face; but he said to me, “Son of man, understand that the vision pertains to the time of the end.”

He said to me, “O Daniel, man of high esteem, understand the words that I am about to tell you and stand upright, for I have now been sent to you.” And when he had spoken this word to me, I stood up trembling.

Then he said, “Do you understand why I came to you? But I shall now return to fight against the prince of Persia; so I am going forth, and behold, the prince of Greece is about to come.

As for me, I heard but could not understand; so I said, “My lord, what will be the outcome of these events?”

Many will be purged, purified and refined, but the wicked will act wickedly; and none of the wicked will understand, but those who have insight will understand.
