1748. That from a thread even to the thong [or latchet] of a shoe. That this signifies all natural and corporeal things that were unclean, is evident from the signification of “the thong of a shoe.” In the Word the sole of the foot and the heel signify the ultimate natural (as before shown, n. 259). A shoe is that which covers the sole of the foot and the heel; a “shoe” therefore signifies what is natural still further, thus the corporeal itself. The signification of a “shoe” is according to the subject. When predicated of goods it is taken in a good sense; and when of evil, in a bad sense; as here in treating of the substance of the king of Sodom, by whom evil and falsity are signified, the “thong of a shoe” signifies unclean natural and corporeal things. By the “thread of a shoe” falsity is signified, and by the “thong of a shoe” evil, and this the most worthless of all, because the word is a diminutive.

[2] That such things are signified by a “shoe,” is evident also from other passages in the Word; as when Jehovah appeared to Moses out of the midst of the bush, and said to Moses:

Draw not nigh hither; put off thy shoes from off thy feet, for the place whereon thou standest is holy ground (Exodus 3:5).

The prince of the army of Jehovah said in like manner to Joshua:

Put off thy shoe from off thy foot; for the place whereon thou standest is holiness (Josh. 5:15).

Here everyone can see that the shoe would take away nothing from the holiness, provided the man were holy in himself; but that it was said for the reason that the shoe represented the ultimate natural and corporeal which was to be put off.

[3] That it is the unclean natural and corporeal, is also plain in David:

Moab is my washpot, upon Edom will I cast My shoe (Psalms 60:8).

The command to the disciples involves what is similar:

Whosoever shall not receive you, nor hear your words, as ye go out of that house or that city, shake off the dust of your feet (Matthew 10:14; Mark 6:11; Luke 9:5); where the “dust of the feet” has a signification like that of a “shoe,” namely, uncleanness from evil and falsity, because the sole of the foot is the ultimate natural. They were commanded to do this because they were at that time in representatives, and thought that heavenly arcana were stored up in these alone, and not in naked truths.

[4] Because a “shoe” signified the ultimate natural, the putting off of the shoe, or the shoe-loosing, signified that one should be divested of the ultimate things of nature; as in the case of him who was not willing to fulfill the duty of brother-in-law, spoken of in Moses:

If the man is not willing to fulfill the duties of a husband’s brother, then his brother’s wife shall come unto him in the eyes of the elders, and draw his shoe from off his foot, and spit in his face; and she shall answer and say, So shall it be done to the man that doth not build up his brother’s house. And his name shall be called in Israel, The house of him that hath his shoe taken off (Deuteronomy 25:5-10);

meaning that which is devoid of all natural charity.

[5] That a “shoe” signifies the ultimate natural, in a good sense also, is likewise evident from the Word; as in Moses, concerning Asher:

Blessed be Asher above the sons; let him be acceptable unto his brethren, and let him dip his foot in oil; iron and brass shall thy shoe be (Deuteronomy 33:24-25); where the “shoe” denotes the ultimate natural; a “shoe of iron” natural truth, a “shoe of brass” natural good, as is evident from the signification of iron and brass (see n. 425, 426). And because a “shoe” signified the ultimate natural and corporeal, it became a symbol of what is least and most worthless; for the ultimate natural and corporeal is the most worthless of all things in man. This was meant by John the Baptist, when he said,

There cometh One that is mightier than I, the latchet of whose shoes I am not worthy to unloose (Luke 3:16; Mark 1:7; John 1:27).

426. That “iron” signifies natural truth, is further evident from what Ezekiel says of Tyre:

Tarshish was thy trader by reason of the multitude of all riches; in silver, iron, tin, and lead, they gave thy traffickings. Dan, and Javan, and Meusal furnished bright iron in thy tradings; cassia and calamus were in thy mart (Ezekiel 27:12, 19).

From these words, as well as from what is said both previously and subsequently in the same chapter, it is very evident that celestial and spiritual riches are signified; and that every particular expression, and even the names mentioned, have some specific signification, for the Word of the Lord is spiritual, and not verbal.

[2] In Jeremiah:

Can one break iron, even iron from the north, and brass? Thy substance [facultates] and thy treasures will I give for a spoil without price, and this for all thy sins (Jeremiah 15:12-13),

where “iron” and “brass” signify natural truth and good; that it came from the “north” signifies what is sensuous and natural; for what is natural, relatively to what is spiritual and celestial, is like thick darkness (that is, the “north”) relatively to light or the “south;” or like shade, which is also signified here by “Zillah” who is the “mother.” That the “substance” and “treasures” are celestial and spiritual riches, is also very evident.

[3] Again in Ezekiel:

Take thou unto thee a pan of iron, and set it for a wall of iron between thee and the city, and set thy faces toward it, and let it be for a siege, and thou shalt straiten against it (Ezekiel 4:3),where also it is evident that “iron” signifies truth. Strength is attributed to truth, because it cannot be resisted, and for this reason it is said of iron-by which is signified truth, or the truth of faith-that it “breaks in pieces” and “crushes”; as in Daniel 2:34, 40, and in John:

He that overcometh, to him will I give sovereign power over the nations, that he may pasture them with a rod of iron; as the vessels of a potter shall they be broken to shivers (Revelation 2:26-27).

Again:

The woman brought forth a man child, who should pasture all nations with a rod of iron (Revelation 12:5).

[4] That a “rod of iron” is the truth which is of the Word of the Lord, is explained in John:

I saw heaven open, and behold a white horse, and He that sat upon him was called Faithful and True, and in righteousness He doth judge and fight; He was clothed with a vesture dipped in blood, and His name is called the Word of God; out of His mouth goeth a sharp sword, that with it He should smite the nations; and He shall pasture them with a rod of iron (Revelation 19:11, 13, 15).
