Arcana Coelestia #1415
1415. Verse 2 And I will make you into a great nation, and I will bless you, and I will make your name great; and you will be a blessing. 'I will make you into a great nation' means a kingdom in heaven and on earth - the expression 'great nation' being used from things that are celestial and good. 'And I will bless you' means fruitfulness in celestial and increase in spiritual things. 'And I will make your name great' means glory. 'And you will be a blessing' means that from the Lord comes every single thing.
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.
