3177. Daß „Jehovah hat gelingen lassen meinen Weg“, 1 Mose 24:56, bedeutet, alles sei nun vorgesehen, kann erhellen ohne Erklärung; denn daß Jehovah den Weg gelingen läßt heißt, Er tut Fürsorge, hier in betreff des Wahren, das verbunden werden soll dem Guten, denn durch Weg wird bezeichnet das Wahre: Nr. 627, 2333.

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.
