On account of the greatness of your iniquity your skirts have been uncovered, your heels have suffered violence. Can the Ethiopian change his skin and the leopard its spots? Also are you able to do good, having been taught to do evil? Jer 13:22, 23.

Here 'skirts' means external truths, 'heels' the lowest goods - 'the heel' and 'shoes' being the lowest natural things, see 259, 1748. And because those truths and goods, as it is said, spring from evil, they are compared to an 'Ethiopian', who was black, and his 'skin', and also to 'a leopard and its spots'.

[2] In Moses,

If you take your neighbour's clothing as a pledge you shall restore it to him before the sun goes down; for this is his only covering; it is his clothing for his skin, in which he will lie down Exod 22:26, 27.

Inasmuch as all the laws contained in the Word, including civil and judicial ones, have a correspondence with laws in heaven concerning what is good and true, and from this correspondence came to be laid down, so it was with the law just quoted. For why else would it have ever been laid down that they were to restore clothing that had been pledged before the sun went down, and why else is it said that 'it is his clothing for his skin, in which he lies down'? The correspondence is evident from the internal sense, which is that people were not to cheat their neighbour of external truths, which are the matters of doctrine by which they conduct their lives, and also religious observances - 'clothing' meaning such truths, see 297,1073, 2576, and 'the sun' the good of love or of life that ensues from those truths, 1529, 1530, 2441, 2495. The prevention of that good from perishing is meant by the statement about the restoration of the pledge before the sun went down. And since the things laid down in those laws are the external coverings of interior things, or the outermost aspects of these, the words 'his clothing for his skin in which he lies down' are used.

[3] Because 'skins' meant external things it was commanded that there should be for the tent a covering made of red ram skins and over that a covering of badger skins, Exod 26:14. For the tent was representative of the three heavens, and so of the celestial and spiritual things of the Lord's kingdom. The curtains enveloping it represented natural things, which are external, 3478; and these are the ram skins and the badger skins. And since external things are those which cover internal, or natural things are those which cover spiritual and celestial, in the way that the body does the soul, that command was therefore given. It was for a like reason commanded that when the camp was on the move Aaron and his sons were to cover the ark of the testimony with the veil and were to place a badger-skin covering over it. And over the table and what was on it they were to spread a twice-dyed scarlet cloth and then cover that with a badger-skin covering. They were likewise required to place the lampstand and all its vessels under a covering made of badger skin - also all the vessels for ministering they were to place under a violet cloth, and then cover them with a badger-skin covering, Num 4:5, 6, 8, 10-12. Anyone who thinks about the Word in a devout way may see that Divine things were represented by all these objects, such as the ark, the table, the lampstand, and the vessels for ministering, also the coverings of twice-dyed scarlet and of violet, as well as the coverings of badger skin, and that these objects represented Divine things contained within external ones.

[4] Because the prophets represented those who teach, and therefore represented teaching from the Word concerning what is good and true, 2534; and because Elijah represented the Word itself, 2762, as also did John, who for that reason is called the Elijah who is to come, Matt 17:10-13; and in order that these might represent the nature of the Word in its external form, that is, in the letter,

Elijah wore a skin girdle around his loins. 2 Kings 1:8. And John had a garment of camel hair and a skin girdle around his waist. Matt. 3:4.

Because animal 'skin' and human 'skin' means external things, which in relation to spiritual and celestial are natural things, and because it was customary in the Ancient Church to speak and to write by means of meaningful signs, reference is also made to both types of skin, and with the same meaning, in Job, a book of the Ancient Church. This becomes clear from a number of places in that book, including the following,

I know my Redeemer; He is alive; and at the last He will rise above the dust; and afterwards these things will be encompassed by my skin, and out of my flesh shall I see God. Job 19:25, 26.

'Encompassed by skin' stands for the natural as it exists with someone after he has died, dealt with in 3539. 'Out of one's flesh seeing God' is doing so from a proprium made alive. For the proprium is meant by 'flesh', see 148, 149, 780; and the Book of Job is a book of the Ancient Church, a fact which is evident, as has been stated, from its style which draws on representatives and meaningful signs. It is not however one of the books called the Law and the Prophets, the reason being that it has no internal sense in which the one subject is the Lord and His kingdom. For it is this alone that determines whether any book is a Book of the true Word.
