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.

3332. 'Jacob gave Esau bread and lentil pottage' means that the good of life was given the good of truth and the good of doctrine. This is clear from the representation of 'Esau' as the good of life, dealt with in 3300, 3322; from the meaning of 'bread' as in general the good of love - both celestial and spiritual good - dealt with in 276, 680, 2165, 2177, and so also the good of truth, this being spiritual good; and from the meaning of 'lentil pottage' as the good of doctrine, for 'pottage' or soup means the massing together of matters of doctrine, 3316, but 'lentils' the good that exists essentially in these. Jacob's giving them to Esau means in the internal sense that those goods come through the doctrine of truth, which Jacob represents, 3305.

[2] These words and those that follow in this final verse describe progress made in regard to truth and good. They describe the situation with the spiritual man while being regenerated, that is to say, how he first learns matters of doctrine concerning truth; how next he is stirred by an affection for them, which is the good of doctrine; how after that, through insight into the matters of doctrine, he is stirred by an affection for the truths which they hold within them, which is the good of truth; and how at length he desires to live according to them, which is the good of life. Thus while undergoing regeneration the spiritual man advances from the doctrine of truth towards the good of life. But once he has reached that point the order is reversed - that good is the point from which he sees the good of truth, the latter the point from which he sees the good of doctrine, and this good in turn the point from which he sees matters of doctrine concerning truth. From these considerations it may be known how, from being sensory-minded, a person becomes spiritual, and what he is like when he has become spiritual.

[3] Those varieties of good, that is to say, the good of life, the good of truth, and the good of doctrine, are all distinct from one another, as becomes clear to those who weigh the matter up. The good of life is that which issues from the will, the good of truth that which issues from the understanding, while the good of doctrine is that which issues from knowledge. Doctrinal teaching is such that it includes all three. It is clear that 'lentils' means the good of doctrine from the fact that wheat, barley, beans, lentils, millet, and spelt are such things as are meant by bread, though with specific differences. The fact that 'bread' in general means good is evident from what has been stated and shown in 276, 680, 2165, 2177; and so specific kinds of good are meant by the grains and beans that have been mentioned - nobler kinds of good by wheat and barley, but less noble by beans and lentils, as also becomes evident from these words in Ezekiel,

You, take for yourself wheat and barley, and beans and lentils, and millet and spelt, and put them into a single vessel, and make them into bread for yourself. Ezekiel 4:9, 12-13.
