3146. 'And gave straw and fodder to the camels' means instruction in truths and goods. This is clear from the meaning of 'straw' as the truths present in the natural man, and from the meaning of 'fodder' as the goods there, dealt with above in 3114. Since these things are meant by 'straw and fodder' it therefore follows that 'giving straw and fodder' is giving instruction in truths and goods. The purpose of that freedom is this: Possessing the affection for truth and being stirred by that affection, a person may become instructed in such a way that truths are implanted deep within him - within the spiritual man or the soul - where they are joined to good, as may be seen from what has been shown regarding freedom in 2870-2893.

[2] This is the way in which faith - that is, truth which is the truth of faith made to take root; and unless it is coupled to good in the rational the truth of faith never receives any life, nor does any fruit develop from it. For everything called the fruit of faith is the fruit of that good which is the good of love and charity coming by way of truth which is the truth of faith. Unless spiritual warmth, which is the good of love, is actively present in spiritual light, which is the truth of faith, man would be like ground frozen stiff, as in wintertime, when nothing grows, let alone bears any fruit. For just as light devoid of warmth is totally unproductive, so is faith devoid of love.

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.
