Arcana Coelestia # 5509
5509. 'Saying' means perception. This is clear from the meaning of 'saying' in the historical narratives of the Word as perceiving, often dealt with already.
Isaiah 6:9-10

He said, "Go, and tell this people, 'You hear indeed, but don't understand; and you see indeed, but don't perceive.'
10
Make the heart of this people fat. Make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their heart, and turn again, and be healed."
