Arcana Coelestia # 9535
9535. 'And you shall make a rim of gold for its rail round about' means the border of the sphere of Divine Good. This is clear from the meaning of 'a rim of gold' as the border of the sphere of Divine Good, as above in 9533; and from the meaning of 'its rail' as the joining to truth from the Divine, in keeping with what has been shown immediately above in 9534.
Arcana Coelestia # 9532
9532. 'And you shall overlay it with [pure] gold' means a representative sign of that good out of mercy. This is clear from the meaning of 'overlaying with gold' as a representative sign of good; for 'gold' means the good of love, 113, 1551, 1552, 5658, 6914, 6917, and therefore that good was represented by the gold where it was applied as a gilding. The reason why it is out of mercy is that all the good of love arises out of mercy, which too is meant by the shittim wood that was overlaid with gold, 9528.
