28. The reason “the Son of Humanity” means the Lord as the Word was that the prophets were also called “children of humanity.” The reason they were called this is that they represented the Lord as the Word and therefore meant the teaching of the church drawn from the Word. That is exactly what people in heaven understand by “prophets” when they are mentioned in the Word. The spiritual meaning of “prophet” and also of “son of humanity” is the teaching of the church drawn from the Word, and when it is said of the Lord, it means the Word itself.

For the prophet Daniel being called a son of humanity, see Daniel 8:17.

For the prophet Ezekiel being called a son of humanity, see 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, 27; 13:2, 17; 14:3, 13; 15:2; 16:2; 17:2; 20:3-4, 27, 46; 21:2, 6, 9, 12, 14, 19, 28; 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.

We can see from this that the Lord as the Divine-Human One is called “the Son of God, ” and as the Word is called “the Son of Humanity.”

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.
