557. Verse 12. For this rejoice, ye heavens, and ye that dwell in them, signifies a new state of heaven, in that they are in the Lord, and the Lord in them. By "heavens" is meant the heaven of Christians, in which the Lord alone is acknowledged as the God of heaven and earth; by "rejoice" is signified its new state full of joy; by "they that dwell" are signified they who are in good (n. 380); and because all good is from the Lord, it signifies that they are in the Lord, and the Lord in them.
