28. The Son of man symbolizes the Lord in relation to the Word because prophets also were called sons of man. Prophets were also called sons of man because they represented the Lord in relation to the Word, and therefore they symbolized the doctrine of the church drawn from the Word. Prophets have no other meaning in heaven when they are mentioned in the Word. For the spiritual meaning of a prophet, as also that of the Son of man, is the doctrine of the church drawn from the Word, and when referring to the Lord it is the Word itself.

That the prophet Daniel was called son of man may be seen in Daniel 8:17.

That the prophet Ezekiel was called son of man may be seen in Ezekiel 2:1, 3, 6, 8, 3:1, 3-4, 10, 17, 25, 4:1, 16, 5:1, 6:2, 7:2, 8:5-6, 8, 12, 15, 11:2, 4, 15, 12:2-3, 9, 18, 22, 27, 13:2, 17, 14:3, 13, 15:2, 16:2, 17:2, 20:3-4, 27, 46, 21:7, 11, 14, 17, 19, 24, 22:18, 24, 23:2, 36, 24:2, 16, 25, 25:2, 26:2, 27:2, 28:2, 12, 21, 29:2, 18, 30:2, 21, 31:2, 32:2, 18, 33:2, 7, 10, 12, 24, 30, 34:2, 35:2, 36:1, 17, 37:3, 9, 11, 16, 38:2, 14, 39:1, 17, 40:4, 43:7, 10, 18, 44:5.

It is apparent now from this that the Lord in relation to His Divine humanity is called the Son of God, and in relation to the Word the Son of man.

In most cases, "mouth" in the Bible represents thought and logic, especially the kind of active, concrete thought that is connected with speech. The reason for this is pretty obvious, but it also holds when people, for instance, remove a stone from the mouth of a well, which represents gaining access to spiritual ideas. The mouth is used for eating as well as speaking, of course. In those circumstances, it represents our first, most external perception of a new spiritual idea or desire. This also makes sense, mirroring the way tasting food in the mouth gives us an instant impression of the quality of the food.
