251. The reason why the “serpent” means all evil in general, and specifically the love of self, is that all evil has had its rise from that sensuous part of the mind, and also from that memory-knowledge [scientifico], which at first were signified by the “serpent;” and therefore it here denotes evil of every kind, and specifically the love of self, or hatred against the neighbor and the Lord, which is the same thing. As this evil or hatred was various, consisting of numerous genera and still more numerous species, it is described in the Word by various kinds of serpents, as “snakes” “cockatrices” “asps” “adders” “fiery serpents” “serpents that fly” and “that creep” and “vipers” according to the differences of the poison, which is hatred. Thus we read in Isaiah:

Rejoice not thou, whole Philistia, because the rod which smiteth thee is broken, for out of the serpent’s root shall go forth a cockatrice, and his fruit shall be a flying fire-serpent (Isaiah 14:29).The “serpent’s root” denotes that part of the mind, or that principle, which is connected with the senses and with memory-knowledge [est sensuale et scientificum]; the “cockatrice” denotes evil originating in the falsity thence derived; and the “flying fire-serpent” the cupidity that comes from the love of self. By the same Prophet also similar things are elsewhere thus described:

They hatch cockatrice’s eggs, and weave the spider’s web; he that eateth of their eggs dieth, and when it is crushed there cometh out a viper (Isaiah 59:5).

The serpent described here in Genesis is called in the Revelation the “great and red dragon” and the “old serpent” and also the “devil and satan” that “deceives the whole world” (Revelation 12:3, 9; 20:2), where, and also in other places, by the “devil” is not meant any particular devil who is prince over the others, but the whole crew of evil spirits, and evil itself.

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.
