3112. 'And she said to him, I am the daughter of Bethuel, the son of Milkah, whom she bore to Nahor' means the whole origin of it, that is to say, of the affection for truth. This is clear from the representation of 'Bethuel', and also of 'Milkah and Nahor', as the origin of the affection for truth which Rebekah represented, see 3078.

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.
