119. That 'Asshur' means the rational mind, that is, a person's rational, is quite clear in the Prophets, as in Ezekiel,

Behold, Asshur was a cedar in Lebanon, beautiful in its branches, and a forest shade, and of a great height, and its top among thick boughs. The waters caused it to grow, the depth of the water; made it tall, a river leading round about the place of its plantings. Ezekiel 31:3-4.

The rational is called 'a cedar in Lebanon'. 'The top among thick boughs' means facts in the memory, this being an apt description of them.

This is clearer still in Isaiah,

On that day there will be a highway from Egypt to Asshur, and Asshur will come into Egypt and Egypt into Asshur, and the Egyptians will serve Asshur. ¹ On that day Israel will be the third with Egypt and Asshur, a blessing in the midst of the earth, whom Jehovah Zebaoth will bless, saying, Blessed be Egypt My people, and Asshur the work of My hands, and Israel My heritage. Isaiah 19:23-25.

Here and in many other places 'Egypt' means knowledge, 'Asshur' reason, and 'Israel' intelligence.

1150. That 'the sons of Japheth' means those who possessed external worship corresponding to internal has been stated already. It is called external worship corresponding to internal when the worship has what is essential within it. And that which is essential is adoration of the Lord from the heart, which in no sense exists unless charity, or love towards the neighbour, is present. It is in charity or love towards the neighbour that the Lord is present, in which case it is possible for Him to be adored from the heart. Thus it is from the Lord that adoration comes, for the Lord makes all adoration possible and gives it all its being. It follows therefore that as is a person's charity, so is his adoration or worship. All worship is adoration, for adoration of the Lord must be in it for it to be worship. The sons of Japheth, that is, the nations and peoples called the sons of Japheth, lived with one another in mutual charity, in friendship, in civility, and in simplicity, and consequently the Lord was present in their worship. For when the Lord is present in external worship internal worship is in that case within the external, that is, there is external worship corresponding to internal. In former times very many nations were such, and nations also exist at the present day who focus worship on external things without knowing what the internal is. And if they do know they give no thought to those matters. If those people acknowledge the Lord and love the neighbour, the Lord is in their worship and they are 'sons of Japheth'. But if they deny the Lord, love only themselves and do not care about the neighbour, worse still if they hate him, then their worship is external separated from internal, and they are 'sons of Canaan' or Canaanites.
