3032. „Und Abraham sprach zu ihm“, 1 Mose 24:6, daß dies das Innewerden des Herrn aus dem Göttlichen bedeutet, erhellt aus der Bedeutung von sprechen, sofern es ist innewerden, wovon Nr. 3029; und aus der vorbildlichen Bedeutung Abrahams, sofern er ist der Herr in Ansehung des Göttlich-Menschlichen, aus dem jenes Innewerden.

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.
