2629. 'Whom Sarah bore to him' means its essential being received from, and its manifestation given by, the Divine spiritual united to the Divine celestial. This is clear from the meaning of 'bearing' as giving manifestation to, dealt with in 2621; and since childbirth implies conception - and the giving of birth, or manifestation, rests with the Divine spiritual, while conception or the imparting of being rests with the Divine celestial, and these are united here - 'bearing' here means the receipt of being as well as the gift of manifestation; and also from the representation of 'Sarah' as the Divine spiritual united to the Divine celestial, dealt with in 1468, 1901, 2063, 2065, 2172, 2173, 2198, 2507. These arcana are so deep that they defy description, so deep in fact that they cannot be illustrated by anything at all in this world. They are intended for the minds of angels, to which they are presented in the light of heaven by means of things which lie beyond description.

2507. 'Of Sarah his wife' means spiritual truth joined to the celestial. This is clear from the meaning of 'Sarah his wife' as intellectual truth joined to Divine Good, or what amounts to the same, spiritual truth joined to the celestial, dealt with in 1468, 1901, 2063, 2065, 2172, 2173, 2198. What the spiritual is, and what the celestial, has been stated quite often already, see 1155, 1577, 1824, 2048, 2088. That is called the celestial which consists in good, that is, which consists in love to the Lord and in charity towards the neighbour; and that is called the spiritual which consists in truth, that is, which consists in faith deriving from love and charity.
