3210. 'And Isaac brought her into the tent of Sarah his mother' means the sanctuary of truth within the Divine Human. This is clear from the meaning of 'a tent' as that which is holy, dealt with in 414, 1102, 2145, 2152, 2576, and so the sanctuary; and from meaning of 'Sarah his mother' as Divine truth, dealt with in 1468, 1901, 2063, 2065, 2904, from which the Divine Human was born, the Rational of which is represented by 'the son Isaac'. From this it is evident that 'Isaac brought her into the tent of Sarah his mother' means that rational Good guided Truth represented by Rebekah into the sanctuary of truth. What the sanctuary of truth is becomes clear from what has been stated above in 3194 about the Lord's Divine Human - that Good and Truth belong essentially to the Divine itself, but that the Lord's Divine Human came into existence from Divine Good and was born (as to the Divine itself, that is) from Divine Truth; or what amounts to the same, that the Lord's Essential Being (Esse) was Divine Good, but the Manifestation (Existere) of Him was Divine Truth. From this came Divine Rational Good to which He joined Divine Truth from the Human.

[2] It is impossible to say anything more about this very deep arcanum than this: Divine Good and Truth themselves within the Lord's Divine Human to which Truth from the Human was joined are what were meant by the Sanctuary or Holy of Holies in the Tabernacle and in the Temple. The nature of that Good and Truth was represented by the objects within the Sanctuary, such as the golden altar, the table with the loaves of the presence, and the lampstand; and further within, by the Mercy Seat and the Ark; and within it, inmostly, by the Testimony which was the Law delivered from Sinai. This was the Holy of Holies itself or Sanctuary of Truth.

Generally, doors in the Bible represent the initial desires for good and concepts of truth that introduce us to new levels of love and understanding, and even to the Lord Himself. Since a “house” represents a person’s desires, affections and passions, the door serves to introduce true ideas that can put those desires into action.

In John 10:7, the door signifies the Lord, who is good itself and truth itself. (Arcana Coelestia 2356[2])

In Revelation 3:8; 4:1, the door signifies admission to the arcana of heaven revealed. (Apocalypse Explained 260[2])

The meaning depends on context, of course. For example, references to doorposts and lintels are making a distinction between introductory goods and introductory truths. And, in Sodom, Lot's house had two doors -- an inner one and an outer one. When, in Genesis 19:6, Lot tried to convince the men of Sodom not to attack the angels visiting him, he went outside the inner door, but stayed inside the outer door. There, the outer door represents a desire for good that is resistant to the falsity represented by the men of Sodom; the inner door represents true ideas springing from that desire for good. Someone nurturing a desire for good could be admitted through the first door, but would have to learn the truth about how to express that desire before being admitted through the second.
