4116. 'And crossed the river' means a state in which a joining together takes place. This is clear from the meaning of 'the river', which in this case is the Euphrates, as a joining together, namely a joining to the Divine. The reason 'the river' has this meaning here is that it was the boundary separating the land of Canaan from that region, and all the boundaries of the land of Canaan were representative of and consequently meant spiritually that which came last and yet first - last because that was where it came to an end, and first because it was where it began. For all boundaries are such that they come last for those who are going out of the country but first for those who are coming in. Because Jacob was at that point coming in, that river was the first boundary that he crossed, and so means a joining together - in the highest sense a joining to the Divine; for 'the land of Canaan' in the internal sense means the Lord's heavenly kingdom, 1607, 3481, and in the highest sense the Lord's Divine Human, 3038, 3705. From all this one may see what is meant here by 'he crossed the river'. For all things in the land of Canaan were representative, with distances, positions, and boundaries determining their individual representations, see 1585, 3686; thus the rivers which served as boundaries, such as the river of Egypt, the river Euphrates, and the river Jordan, were representative, 1866.

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.
