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.

7408. And they gathered them together in heaps and heaps. That this signifies that these false reasonings were arranged in bundles in the natural, is evident from the signification of “being gathered together in heaps and heaps,” as being to be arranged in bundles. That “to be gathered together in heaps” denotes these things, is because all things in the mind of man have been arranged into series, and as it were into bundles; and into series within series, or into bundles within bundles (see n. 5339, 5530, 5881). That there is such an arrangement, is plain from the arrangement of all things in the body, where fibers are seen arranged into bundles, and glandules into clusters, and this everywhere in the body, and still more perfectly in the purer parts not discernible by the naked eye. This bundling is especially to be seen in the brain, in the two substances there, one of which is called cortical and the other medullary. It is not dissimilar in the purer things, and finally in the purest of all, where the forms which receive them are the very forms of life.

[2] That forms or substances are recipient of life can be seen from every single thing that appears in living creatures; and also that recipient forms or substances are arranged in the way most suitable for the influx of life. Without the reception of life in substances, which are forms, there would be no living thing in the natural world, nor in the spiritual world. Series of the purest filaments, like bundles, constitute these forms. It is the same with those things therein which are highly modified; for modifications receive their form from the forms which are the substances in which they are, and from which they flow, because the substances or forms are the determining subjects. The reason why the learned have regarded the things belonging to man’s life, that is, to his thought and will, as being devoid of recipient substances or forms, has been that they believed life or the soul to be something either flamy or ethereal, thus such as after death would be dissipated; hence comes the insane notion of many, that there is no life after death. From all this it is evident how it is to be understood that the reasoning falsities were arranged in groups in the natural.
