Arcana Coelestia #9676
9676. 'And their hooks [shall be made] from gold' means the modes by which they are linked together through good. This is clear from the meaning of 'hooks' as the modes by which things are linked together, hooks possessing this meaning on account of their shape; and from the meaning of 'gold' as good, dealt with in 113, 1551, 1552, 5658, 6914, 6917, 9490.
Arcana Coelestia #1552
1552. 'And gold' means goods deriving from truths. This is clear from the meaning of 'gold' as celestial good, or the good of wisdom and love, as is clear from what has just been shown and also from what was shown previously in 113. That here they are goods deriving from truths follows from what was stated in the previous chapter about the Lord's joining intellectual truths to celestial things.
