Aaron
Aaron was the brother of Moses. He symbolizes two things, at different stages of the story.
During the first part of the exodus, when he was Moses' spokesperson, Moses represents the Word as it truly is, as it is understood in heaven, while Aaron represents the Word in its external sense, as it is understood by people in the world. This is why Aaron talks for Moses, and the Lord says of him "he shall be as a mouth for you, and you shall be to him as God." (Exodus 4:16)
Later, after the Tabernacle was built and he was inaugurated as high priest (see Leviticus 8,9), Aaron represents the Lord as to the Divine Good, and Moses represents the Lord as to the Divine Truth.
In Exodus 28:1, Aaron signifies the conjunction of Divine Good with Divine Truth in the Divine Human of the Lord. (Arcana Coelestia 9806, 9936)
In Exodus 32:1, Aaron represents the external of the Word, of the church, and of worship, separate from the internal. (Arcana Coelestia 10397)
In Exodus 4:14, before he was initiated into the priesthood, Aaron represents the doctrine of good and truth. (Arcana Coelestia 6998)
Matthew 7:11-24
11
If you then, being evil, know how to give good gifts to your children, how much more will your Father who is in heaven give good things to those who ask him!
12
Therefore whatever you desire for men to do to you, you shall also do to them; for this is the law and the prophets.
13
"Enter in by the narrow gate; for wide is the gate and broad is the way that leads to destruction, and many are those who Enter in by it.
14
How narrow is the gate, and restricted is the way that leads to life! Few are those who find it.
15
"Beware of false prophets, who come to you in sheep's clothing, but inwardly are ravening wolves.
16
By their fruits you will know them. Do you gather grapes from thorns, or figs from thistles?
17
Even so, every good tree produces good fruit; but the corrupt tree produces evil fruit.
18
A good tree can't produce evil fruit, neither can a corrupt tree produce good fruit.
19
Every tree that doesn't grow good fruit is cut down, and thrown into the fire.
20
Therefore, by their fruits you will know them.
21
Not everyone who says to me, 'Lord, Lord,' will enter into the Kingdom of Heaven; but he who does the will of my Father who is in Heaven.
22
Many will tell me in that day, 'Lord, Lord, didn't we prophesy in your name, in your name cast out demons, and in your name do many mighty works?'
23
Then I will tell them, 'I never knew you. Depart from me, you who work iniquity.'
24
"Everyone therefore who hears these words of mine, and does them, I will liken him to a wise man, who built his house on a rock.
