Eyes
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.
Ezekiel 37:9-10
9
Then he said to me, Prophesy to the wind, prophesy, son of man, and tell the wind, Thus says the Lord Yahweh: Come from the four winds, breath, and breathe on these slain, that they may live.
10
So I prophesied as he commanded me, and the breath came into them, and they lived, and stood up on their feet, an exceedingly great army.
