247. 'The serpent going on its belly' means that the sensory part was no longer able to look upwards to celestial things, as previously, only downwards to bodily and worldly things. This is clear from the fact that in earliest times 'the belly' meant things closest to the earth, ‘the breast’ those that were above the earth, and ‘the head’ those that were the highest. This is why in this verse the sensory part, which in itself is the lowest part of man since it directs itself to what is earthly, is referred to as ‘going on its belly’. And in the Jewish Church lying flat with the belly on the ground and sprinkling dust over the head had the same meaning. In David it is said,

Why do You hide Your face ¹ and forget our misery and our oppression? For our soul is bowed down to the dust, and our belly cleaves to the ground. Rise up, as a help for us, and redeem us for Your mercy's sake. Psalms 44:24-26.

Here too it is clear that when a person turns away from the face of Jehovah he starts to cling with his belly to the dust and the ground. In Jonah also the belly of the great fish into which he was cast means the lower parts of the earth, as is clear from his own prophecy,

Out of the belly of hell I cried, and You did hear my voice. Jonah 2:2.

Here 'hell' stands for the lower earth.

Footnotes:

The sun in the Bible represents the Lord, with its heat representing His love and its light representing His wisdom. “Daytime,” then, represents a state in which we are turned toward the Lord, receiving His love and being enlightened by His truth. And “nighttime,” obviously, represents states in which we are turned away from the Lord, left cold and blind to the truth. The most common word used for it in the New Christian theology is “obscurity.” The darkness is not absolute, of course. The light of the moon represents the understanding we can have based on facts and our own intelligence. But while the moon reflects some of the sun's light, it offers almost no heat, so this kind of understanding is a cold one, without the warmth of love. And at its darkest and coldest, night represents a state of judgment. This happens when a person -- or a church -- becomes so mired in evil and falsity that there is no light or heat. The Lord can then step in, separate the good from the evil, consign the evil to hell and begin rebuilding based on the remnant that is still good. Drastic as that sounds, it is something that we all go through repeatedly in various aspects of our loves, so that we can be rid of what is evil and let the Lord rebuild us as angels.
