9653. 'And for the two legs of the dwelling-place towards the sea' means a joining to heaven where good dwells in obscurity. This is clear from the meaning of 'two' as a joining together, as above in 9645; from the meaning of 'the legs' as the borders where good dwindles into obscurity, dealt with in 7859; from the meaning of 'the dwelling-place' as heaven, dealt with in 9594; and from the meaning of the west or 'the sea' as a state of good in obscurity, dealt with in 3708, 8615. This state is meant by 'the west' because the Lord in respect of the good of love is meant by 'the sun', 3636, 3643, 4060, 4321 (end), 7078, 7083, 7171, 8644, 8812. Therefore 'the east' where the sun rises means the good of love from the Lord where the perception of it is clear, and 'the west' where the sun goes down means good from Him where the perception of it is obscure. And since a person's and an angel's perception is clear when they have been raised towards more internal parts or into the light of heaven, and their perception is obscure when they remain in more external parts, 9648, thus when they remain in the light of the world, the west is also called the sea. For 'the sea' means factual knowledge in general, 28, 2850, and factual knowledge resides in the external or natural man, where good lies in obscurity. All factual knowledge, since it belongs to the natural man, dwells in the light of the world.

7859. 'Its head over its legs and over its middle' means from what is inmost to what is external. This is clear from the meaning of 'the head', when said to be 'over the head and middle', as what is inmost, for the head is on top, and what is on top is in the spiritual sense what is inmost, 2148, 3084, 4599, 5146 (for the meaning of 'the head' as the interiors and 'the body' as the exteriors, see 6436); from the meaning of 'the legs' as exteriors, for in relation to the head the legs are lower, and just as higher parts mean more internal ones, so lower parts mean more external ones; and from the meaning of 'the middle' as the parts that are lower still, as those of the belly and intestines are. The command that they were to roast the head over the legs and over the middle represented the necessity for interiors and exteriors to be combined, that is, to act as one. The interiors are what constitute the internal man, the exteriors what constitute the external man; or, the interiors are what constitute the spiritual man, while the exteriors are what constitute the natural man. These must be combined, that is, act as one, if a person is to have the Lord's kingdom within him. They are separated when the natural or external man acts differently from what the spiritual or internal man desires. These considerations go to prove what was meant by the regulation that the Passover lamb should be roasted with fire, the head over the legs and middle. 'The middle' is used to mean the even more external part of the natural, which is the level of the senses. Anyone may see that a Divine arcanum is present within these commands, for the Passover lamb was the most holy thing in that Church. But that holy arcanum is indiscernible except through a spiritual understanding, such as is presented here, of the subject matter involved and the words used.
