Arcana Coelestia # 9882
9882.. 'And you shall make on the breastplate two rings of gold' means a sphere of Divine Good, a sphere through which there is a joining to the higher part of heaven. This is clear from the meaning of 'the breastplate' as a representative sign of heaven, dealt with in 9879; and from the meaning of 'two rings of gold' as a sphere of Divine Good, by which a joining together is accomplished, dealt with in 9498, 9501. The reason why it is a joining to the higher part of heaven is that this is what is meant by the requirement for the rings to be on the upper part of the breastplate; for from there the small chains were taken up to the sockets of gold on the shoulder-pieces of the ephod.
Arcana Coelestia # 9501
9501. 'The poles must be in the rings of the ark' means that the power must be established by the Divine sphere of goodness and truth. This is clear from the meaning of 'the rings of the ark' as the Divine sphere of goodness and truth; and from the meaning of 'the poles' as the power, both dealt with above in 9498.
