In Exodus 26:6, rings, taches, or clasps of gold signify the ability to use good loves to join things together. The gold stands for inner, pure loves for good. (Arcana Coelestia 9624)

Some English translations of the Word use the terms clasps, or taches of gold, and indeed Swedenborg's description of the inner meaning seems to include the idea of clasping, attaching, or joining.

Later in the story, when bronze clasps are mentioned, they mean more external -- though still good -- loves.

(Riferimenti: Arcana Coelestia 9611)

9624. 'And you shall make fifty clasps of bronze' means a complete ability derived from external good to join things together. This is clear from the meaning of 'fifty clasps' as a complete ability to join things together, dealt with above in 9611; and from the meaning of 'bronze' as natural or external good, dealt with in 425, 1551.
