Arcana Coelestia # 9853
9853. 'On the borders you shall make them' means at the most external parts through which influx comes. This is clear from the meaning of 'the borders' as the most external parts. The reason why these are the parts through which influx, the influx of good, comes is that coherence is meant by 'the small chains', 9852, and all coherence in the spiritual world is brought about by means of influx.
Arcana Coelestia # 9851
9851. 'And you shall make sockets of gold' means being brought into being and kept unceasingly in being by good. This is clear from what has been stated above in 9847. The reason why unceasingly is meant is that this is a second mention of 'sockets'.
