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.

2356. That 'Lot went out to them to the door (janua)' means that he acted cautiously is clear from the interior sense of 'the door' and of 'going out to the door'. 'A door' in the Word means that which introduces or leads the way either towards truth, or towards good, or towards the Lord. Consequently 'a door' in addition means truth itself, also good itself, as well as the Lord Himself, for truth leads to good, and good leads to the Lord. Such things were represented by the door and the veils of the Tent of Meeting, and also of the Temple, see 2145, 2152, 2576.

[2] That this is the meaning of 'a door' is evident from the Lord's words in John,

He who does not enter by the door into the sheepfold but climbs in by another way, that man is a thief and a robber. But he who enters by the door is the shepherd of the sheep. To him the doorkeeper opens. I am the door of the sheep; if anyone enters through Me he will be saved. John 10:1-3, 7, 9.

Here 'door' stands for truth and good, and so for the Lord who is truth itself and good itself. This shows what is meant by being let in through the door into heaven, and therefore what is meant by 'the keys' which unlock it.

[3] Here however 'a door' means a particular type of good that was suited to the disposition of those who besieged the house, for a distinction is made here between 'a door' (janua) and 'a door' (ostium). The former was on the outside of the house, as is evident from the fact that Lot went out and closed the door (ostium) behind him. This type of good was blessedness of life, as is clear from what follows shortly where he persuaded those who were immersed in falsity and evil. For such people do not allow themselves to be persuaded by actual good itself; indeed they reject it. From these considerations it is evident that here 'going out to the door' means that he acted cautiously.
