10050. 'And its legs' means purification of the more external things belonging to the natural man. This is clear from the meaning of 'washing the legs' as purification of the natural man (for the meaning of 'washing' as purifying, see immediately above in 10049); and from the meaning of 'the legs' as the more external things belonging to the natural man. The reason why these things are meant by 'the legs' is that one must at the same time understand the feet, since an animal's four legs are closely connected to its feet, and 'the feet' by virtue of their correspondence mean the natural or external level in a person, see 2162, 3147, 3761, 4938-4952.

[2] Much the same is meant by 'the legs' in Amos,

As the shepherd rescues from the mouth of the lion two legs or a piece of an ear, so will the children of Israel dwelling in Samaria be rescued, on the corner of a bed and on the end of a couch. Amos 3:12.

'The lion' here means those who lay the Church waste, 'legs' the external part of it, which is also the external part of the natural man, 'a piece of an ear' its discernment, and those 'dwelling in Samaria' those whose worship is external. 'The corner of a bed and the end of a couch' is the lowest part of the natural, which is external sensory awareness and its truth and good.

[3] In Daniel's description of Nebuchadnezzar's statue - its head made of pure gold, breast and arms of silver, belly and side of bronze, legs of iron, and feet partly of iron and partly of clay, Daniel 2:32-33 - what is meant by 'the legs' is the truth of faith in the external or natural man; and the same thing is also meant by 'iron', see 10030. The reason why the legs in the description are distinguished from the feet is that human legs are by nature different from animal legs.

5328. 'Or his foot' means all power in the natural. This is clear from the meaning of 'foot' as the natural, dealt with in 2162, 3147, 3761, 3986, 4280, 4931-4952. Here power within the natural is meant because 'lifting up the foot', like 'lifting up the hand', means power, though 'lifting up the hand' means power in the spiritual, whereas 'lifting up the foot' means power in the natural; for the parts within the body that are above the feet correspond to spiritual things. This is especially evident from the Grand Man or the three heavens.

[2] Whenever the whole of heaven is displayed visually as one human being, the inmost or third heaven presents itself as the head, the middle or second heaven presents itself as the body, and the lowest or first as the feet. The reason the inmost or third heaven presents itself as the head is that it is celestial; the reason the middle or second heaven presents itself as the body is that it is spiritual; and the reason the lowest or first presents itself as the feet is that it is natural. By 'the neck' therefore, since this is an intermediate part, is meant the inflow and communication of celestial things with spiritual ones; and by 'the knees', since these are likewise intermediate, is meant the inflow and communication of spiritual things with natural ones. From this it is evident that 'lifting up the hand' means power within the spiritual, while 'lifting up the foot' means power within the natural, and therefore that the power meant by 'the hand' has regard to the spiritual, namely to truth grounded in good, 3091, 3567, 4932. By the spiritual is meant that within the natural which belongs to the light of heaven, and by the natural that within the natural which belongs to the light of the world; for everything belonging to the light of heaven is called spiritual, and everything belonging to the light of the world is called natural.
