1584. That 'Lot lifted up his eyes' means that the external man received light from the internal is clear from the meaning of 'lifting up the eyes', which is seeing, in the internal sense, perceiving. Here 'lifting up the eyes' means receiving light, for this expression is used in reference to Lot, or the external man; and by perceiving the nature of the External Man when joined to the Internal Man, that is, the nature of its beauty, the external man receives light from the internal and possesses the Divine vision that is the subject here. Nor can there be any doubt that when He was a boy, the Lord as regards His external Man frequently had such Divine vision, for He alone was to join the external Man to the internal Man. The External Man was His Human Essence, while the Internal Man was His Divine Essence.

120. Like Egypt, the Euphrates too means knowledge or facts, and also sensory evidence from which facts are obtained. This is clear from the Word in the Prophets, as in Micah, She, my enemy, said, Where is Jehovah your God? A day on which He will build your walls. On that day what has been determined will be absent afar off. That day also He will come to you from Asshur, and to the cities of Egypt and to the River (the Euphrates) Micah 7:10-12.

The Prophets spoke in this way when referring to the coming of the Lord, who was going to regenerate man so that he would become as a celestial man. In Jeremiah,

What have you to do with the way to Egypt, to drink the waters of Shihor? And what have you to do with the way to Asshur, to drink the waters of the River (the Euphrates)? Jeremiah 2:18.

Here similarly 'Egypt' and 'the Euphrates' stand for facts, and 'Asshur' for reasonings based on them. In David,

You did cause a vine to journey out of Egypt. You did cast out the nations, You did plant it. You did send out its shoots even to the sea, and its little branches to the River (the Euphrates) Psalms 80:8, 11.

Here too 'the river Euphrates' stands for sensory evidence and factual knowledge. Indeed the Euphrates was the boundary to Israel's territories in the direction of Asshur, just as factual knowledge in the memory is the boundary of intelligence and wisdom of the spiritual and celestial man. The same is meant by these words addressed to Abraham,

To your seed I will give this land, from the river of Egypt even to the great river, the river Euphrates. Genesis 15:18.

Both of these two boundaries have the same meaning.
