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.

10049. 'And wash the intestines' means purification of the lowest things. This is clear from the meaning of 'washing' as purifying, dealt with in 3147, 5954(end), 9088 (the purification that was represented by washing is a purification from evils and falsities, for these are what dirt is in the spiritual sense); and from the meaning of 'the intestines' as lowest things, dealt with above in 10030. The reason why it says that the intestines and legs had to be washed is that lowest things and natural things are meant by them, and lowest and natural things are sullied by evils and falsities, more so than interior ones. For they are based in the world, and the things of the senses - the lowest of all - stand exposed to the world and are therefore in direct receipt of influences from the world. Those influences enter them as the delights of self-love and love of the world, along with the delights of the senses and the illusions of the senses. But this is not so with interior things, for these are not based in the world but in heaven. Furthermore the things of the world cannot pass into those of heaven, for there is no such thing as physical influx; but the things of heaven can pass into those of the world present with a person. Therefore as soon as the external man wishes to enter the internal, which is done by means of reasonings that are products of self-love and love of the world, and products of the illusions of the senses, the internal man is closed; the Lord sees to this. Therefore when a person is being regenerated the purification of the internal man is effected in heaven by the Lord, with the consequence that while in the world the person does not see what is being accomplished in his internal man. These things are the ones that should be understood by the Lord's words in John,

The spirit breathes where it wishes, and you hear its voice; but you do not know where it comes from and where it goes away to. So is everyone who is born from the spirit. John 3:8.

'The spirit' is the life of charity through faith.

4007. 'Every one that had white in it' means that which has truth in it. This is clear from the meaning of 'white' as truth, but strictly speaking as the Lord's Righteousness and Merit, and from this the Lord's righteousness and merit as these exist with man, dealt with in 3301, 3993. 'White' has that meaning because the light of heaven which radiates from the Lord, a light which is the source of splendour and brightness, means truth. Anything therefore on which that light falls and is made splendid and bright is that which is called the Lord's righteousness and merit existing with man. Those who acknowledge this, the Lord's righteousness, and who from good take it to themselves and reject their own, are specifically the ones meant by 'the righteous' whom the Lord refers to, in Matthew,

The righteous will shine like the sun in the kingdom of their Father. Matthew 13:43.

[2] The fact that that which is 'white', being splendid and bright, has this meaning is also evident from other places in the Word, as in Moses,

His eyes will be redder than wine, and his teeth whiter than milk. Genesis 49:12.

This refers to Judah, who represents the Lord as regards the Divinity of His Love, and in the internal sense the celestial kingdom, and so the celestial man, see 3881. 'Eyes redder than wine' means Divine Wisdom, and 'teeth whiter than milk' means Righteousness. In David,

You will purify me with hyssop and I shall be clean; You will wash me, and I shall become whiter than snow. Psalms 51:7.

'Washing and becoming whiter than snow' stands for being purified from sins by means of receiving and putting on the Lord's righteousness. In John,

In the midst of the seven lampstands one like the Son of Man. His head and hair were white, like white wool, like snow; and his eyes were like a flame of fire. Revelation 1:13-14.

[3] In the same book,

You have a few names in Sardis, who have not soiled their garments, and they will walk with Me in white, for they are worthy. He who conquers will be clad in white garments. Revelation 3:4-5.

In the same book,

I counsel you to buy from Me gold purified in fire, that you may be rich, and white garments to clothe you. Revelation 3:18.

In the same book,

To each soul under the altar were given white robes. Revelation 6:9, 11.

In the same book,

I saw, standing before the throne and before the Lamb those clothed in white robes. One of the elders said to me, These clothed in white robes - who are they, and where have they come from? I said to him, Sir, you know. He said to me, These are they who are coming out of the great tribulation, and have washed their robes, and have made their robes white in the blood of the Lamb. Revelation 7:9, 13-14.

In the same book,

The angels were clothed in linen, white and splendid, and were girded around their breasts with golden girdles. Revelation 15:6.

In the same book,

I saw, and behold, a white horse, and he who sat on it had a bow; to him a crown was given. Revelation 6:2.

And elsewhere,

After this I saw heaven opened, and behold, a white horse. His armies in heaven were following Him on white horses and were clothed in linen white and clean. Revelation 19:11, 14.

[4] In all these places 'white' means the truth of faith; 'white garments' and 'white robes' have no other meaning. But the truth of faith does not exist with any who believe that they have faith of themselves and so believe that they are wise of themselves. Rather, it exists with those who believe that their faith and wisdom come from the Lord, for faith and wisdom are imparted to them because they do not ascribe any truth or good at all to themselves. Even less do they believe that they possess any merit through the truths and goods residing with them, and less still any righteousness, but only by ascribing these to the Lord, and so everything to His grace and mercy. This is what 'putting on white garments' means, and also what 'being made white in the blood of the Lamb' means. There are two things which all who enter heaven cast aside, namely their proprium and consequent confidence, and merit that is their own or self-righteousness. Then they assume a heavenly proprium which comes from the Lord, and the Lord's merit or righteousness. And to the extent that these are so assumed those persons advance further into heaven. These two things specifically are meant by 'red' and by 'white'; 'red' means the good of love and is present with those people at that time, 'white' the truth of faith.
