7918. And ye shall take a bunch of hyssop. That this signifies an external means by which there is purification, is evident from the signification of “hyssop,” as being external truth, which is a means of purification (of which in what follows). It is said that they should “take a bunch of hyssop,” because “a bunch” is predicated of truths and their arrangement (n. 5530, 5881, 7408). That “hyssop” denotes external truth as a means of purification, is because all spiritual purification is effected by means of truths. For the earthly and worldly loves from which man is to be purified, are not recognized except by means of truths, and when these are instilled by the Lord, there is also instilled at the same time horror for these loves as for things unclean and damnable, the effect of which is that when anything of the kind flows into the thought, this feeling of horror returns, and consequently aversion for such things. Thus man is purified by truths as by an external means. It was on this account ordered that circumcision should be performed by means of knives or lancets of flint. (That “lancets” or “knives of flint” denote the truths of faith whereby purification is effected, see n. 2799, 7044; and that “circumcision” denotes purification from filthy loves, n. 2039, 2632, 3112, 3413, 4462, 7045)

[2] As “hyssop” has this signification, it was therefore employed in cleansings, which in the internal sense signified purifications from falsities and evils, as in the cleansing of the leprosy, in Moses:

The priest shall take for the leper that is to be cleansed two living clean birds, and cedar wood, and scarlet and hyssop, and shall dip them in the blood of the bird that was killed, and he shall sprinkle upon him that is to be cleansed (Leviticus 14:4-7);

and in like manner “in the cleansing of a house, if the leprosy be in it” (verses 49-51). For preparing the water of separation by which cleansings were wrought, cedar wood and hyssop were also employed (Numbers 19:6, 18); by “cedar wood” was signified internal spiritual truth, and by “hyssop” external; thus by “cedar” an interior means of purification, by “hyssop” an exterior one. That “hyssop” denotes a means of purification is very manifest in David:

Thou shalt purge me with hyssop, and I shall become clean; Thou shalt wash me, and I shall be whiter than snow (Psalms 51:7); where “to be purged with hyssop and made clean” denotes external purification; “to be washed and made whiter than snow,” internal purification; “snow” and “whiteness” are predicated of truth (n. 3301, 3993, 4007, 5319). That “hyssop” denotes lowest truth, and “cedar” highest truth, is plain from these words in the first book of Kings:

Solomon spoke of woods, from the cedar which is in Lebanon even unto the hyssop that goeth out of the wall (1 Kings 4:33); where “cedar” denotes internal truth which is of intelligence; and “hyssop,” external truth which is of intelligence.

4007. Every one that had white in it. That this signifies in which there is truth, is evident from the signification of “white,” as being truth, but properly the Lord’s righteousness and merit, and derivatively the Lord’s righteousness and merit in man (see n. 3301, 3993). The reason why “white” has this signification, is that the light of heaven, which is from the Lord and is the source of brightness and whiteness, signifies truth; and therefore that which is enlightened by that light, and becomes shining and bright, is that which is called the Lord’s righteousness and merit in man. They who from good acknowledge and receive the Lord’s righteousness, and reject their own righteousness, are they who are specifically signified by “righteous,” concerning whom the Lord says in Matthew:

The righteous shall shine as the sun in the kingdom of their Father (Matthew 13:43).

[2] That “shining or bright white” has this signification, is evident also from other passages in the Word; as in Moses:

His eyes shall be redder than wine, and his teeth whiter than milk (Genesis 49:12);

speaking of Judah, by whom is represented the Lord as to the Divine of His love; and in the internal sense, the celestial kingdom; and thus the celestial man (as may be seen above, n. 3881). The “eyes being redder than wine” signifies the Divine wisdom; and the “teeth whiter than milk,” the Divine righteousness.

In David:

Thou shalt purify me with hyssop, and I shall be clean; Thou shalt wash me, and I shall be whiter than snow (Psalms 51:7);

“to wash,” and “to be made whiter than snow,” denotes to be purified from sins by the reception and putting on of the Lord’s righteousness.

In John:

In the midst of the seven candlesticks was one like unto the Son of man; His head and His hairs were white as white wool, as snow; and His eyes were as a flame of fire (Revelation 1:13-14).

[3] In the same:

Thou hast a few names in Sardis who have not defiled their garments, and they shall walk with Me in white, for they are worthy. He that overcometh shall be clothed in white garments (Revelation 3:4-5).

In the same:

I counsel thee to buy of Me gold purified in the fire, that thou mayest be rich; and white garments that thou mayest be clothed (Revelation 3:18).

Again:

There were given to every soul under the altar white robes (Revelation 6:9-11).

Again:

I saw them standing before the throne, and before the Lamb, arrayed in white robes. And one of the elders said unto me, Who are these clothed in white robes? And whence came they? And I said unto him, My lord, thou knowest. And he said unto me, These are they who come 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).

Again:

Angels clothed in linen white and shining, and girt about their breasts with golden girdles (Revelation 15:6).

Again:

I saw and behold a white horse, and he that sat thereon had a bow, and there was given unto him a crown (Revelation 6:2).

And again:

Afterwards I saw heaven opened, and behold a white horse. His armies in heaven followed Him upon white horses, clothed in fine linen white and clean (Revelation 19:11, 14).

[4] In all these passages by “white” is signified the truth of faith; the “white garments” and “white robes” being nothing else. But the truth of faith does not belong to those who believe that they have faith of themselves, and thus are wise from themselves; but to those who believe they have faith and wisdom from the Lord, for to these are faith and wisdom given because they ascribe nothing of truth and good to themselves, still less believe that they have merit through the truths and goods they possess; and less still that they are justified thereby; but only by ascribing them to the Lord; thus all things to His grace and mercy. This is “putting on white garments;” and is also “being made white in the blood of the Lamb.” There are two things that are put off by all who enter into heaven, namely, their own and the consequent confidence, and the merit of self or of their own righteousness; and they put on a heavenly own which is from the Lord, and the Lord’s merit or righteousness; and the more they put on these, the more interiorly do they come into heaven. These two things are specifically signified by “red” and by “white;” by “red,” the good of love which they then have; and by “white,” the truth of faith.
