3163. 'So it was, when Abraham's servant heard their words, that he bowed down to the earth to Jehovah' means the perception of joy in the natural man. This is clear from the meaning of 'hearing the words' as perceiving, from the representation of 'Abraham's servant' as in general the natural man insofar as it is subservient to the rational, here to the Divine, dealt with in 3019, 3020, and from the meaning of 'bowing down to Jehovah' as rejoicing, dealt with in 2927, 2950, 3118.

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.
