'Understand' in the Bible

But they did not understand what He said to them.

So He said, “The secrets of the kingdom of God have been given for you to know, but to the rest it is in parables, so thatLooking they may not see,and hearing they may not understand.

But they did not understand this statement; it was concealed from them so that they could not grasp it, and they were afraid to ask Him about it.

Then He opened their minds to understand the Scriptures.
