It's common to say “I see” when we understand something. And indeed, “seeing” in the Bible represents grasping and understanding spiritual things. So it makes sense that the eyes, which allow us to see, represent the intellect, which allows us to understand spiritual things. This can also be used in the negative, of course; the Bible speaks of people having eyes and refusing to see, and the Lord when He was in the world advised plucking out an offending eye. These represent a refusal to acknowledge truth, or being misled by falsity.

1926. That 'the angel of Jehovah' here is the interior thought which came from the Lord's Internal is clear, as stated, from the train of thought. Here the term interior is used to mean that with the Lord which was united to Jehovah, or His Internal. Union was not accomplished all at once but step by step, that is to say, from earliest childhood through to the last stage of His life in the world, above all by means of temptations and victories. Each temptation and victory brought about union and to the extent He united Himself with His Internal or Jehovah, thought became more interior, and intellectual truth more united to Divine Good. It is the thought such as this that is meant by interior thought flowing from the Lord's Internal and that is specifically represented and meant here by 'the angel of Jehovah'.
