Arcana Coelestia # 63
63. Meanwhile the Lord is constantly fighting on his behalf against evils and falsities and by these conflicts is confirming him in truth and good. The hour of conflict is the hour when the Lord is at work, which is why in the Prophets a regenerate person is called 'the work of God's fingers'. Nor does He rest until love is playing the leading part, at which point conflict ceases. When that work has reached the point where faith has been joined to love, it is then called 'very good', for the Lord then moves him to be a likeness of Himself. At the end of the sixth day evil spirits go away and good ones take their place; then the person is led into heaven, or the heavenly paradise, which is the subject of the next chapter.
Arcana Coelestia # 118
118. Verse 14 And the name of the third river is the Hiddekel. This eastwards towards Asshur. And the fourth river is the Phrath.
'The river Hiddekel' is reason or the sharp-sightedness of reason. 'Asshur' is the rational mind. The river's 'going eastwards towards Asshur' means that the sharp-sightedness of reason comes from the Lord by way of the internal man into the rational mind, which belongs to the external man. 'The Phrath' or the Euphrates is knowledge, which is the extremity or boundary.
