Arcana Coelestia # 2852
2852. Verse 18 And in your seed all the nations of the earth will be blessed because you have hearkened to My voice.
'In your seed all the nations of the earth will be blessed' means the salvation of all who are endowed with good. 'Because you have hearkened to My voice' means through the union of the Lord's Human Essence with His Divine Essence.
Isaiah 14:1-2
1
For the LORD will have mercy on Jacob, and will yet choose Israel, and set them in their own land: and the strangers shall be joined with them, and they shall cleave to the house of Jacob.
2
And the people shall take them, and bring them to their place: and the house of Israel shall possess them in the land of the LORD for servants and handmaids: and they shall take them captives, whose captives they were; and they shall rule over their oppressors.
