'Understand' in the Bible

And He saith, 'Go, and thou hast said to this people, Hear ye -- to hear, and ye do not understand, And see ye -- to see, and ye do not know.

By whom doth He teach knowledge? And by whom doth He cause to understand the report? The weaned from milk, the removed from breasts,

Your perversion! as clay is the potter esteemed? That the work saith of its maker, 'He hath not made me?' And the framed thing said of its framer, 'He did not understand?'

With whom consulted He, That he causeth Him to understand? And teacheth Him in the path of judgment, And teacheth Him knowledge? And the way of understanding causeth Him to know?

Ye are My witnesses, an affirmation of Jehovah, And My servant whom I have chosen, So that ye know and give credence to Me, And understand that I am He, Before Me there was no God formed, And after Me there is none.

They have not known, nor do they understand, For He hath daubed their eyes from seeing, Their heart from acting wisely.
