Arcana Coelestia # 1417
1417. That the expression 'great nation' is used from things that are celestial and good is clear from what has just been stated and shown, and also from what has appeared already in 1259. From this one may see what is meant in the proper sense by the Church among 'the nations'.
Isaiah 9:2-3
2
The people who walked in darkness have seen a great light. Those who lived in the land of the shadow of death, on them the light has shined.
3
You have multiplied the nation. You have increased their joy. They rejoice before you according to the joy in harvest, as men rejoice when they divide the spoil.
