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.

2954. I will give the silver of the field; take it of me. That this signifies redemption as to the truths of the church which are from the Lord, is evident from the signification of “giving silver,” as being to redeem by truth (see above, n. 2937); for “silver” is truth (n. 1551); from the signification of “field,” as being the church, and also the doctrine of truth (see n. 368, 2936); and from the signification of “taking of me,” as being what is reciprocal with those who are of the church; the reciprocal is faith that redemption is from the Lord alone. As regards redemption, it is the same as reformation and regeneration and the consequent deliverance from hell and salvation. The redemption or reformation and salvation of the men of the spiritual church is effected through truth; but that of the men of the celestial church through good. The reasons have been repeatedly stated above, namely, that the spiritual have nothing of the will of good, but in its stead have been gifted with the faculty of understanding what is good. The understanding of good is what is principally called truth, and indeed the truth of faith; but willing and thence doing this is what is called good. The spiritual therefore, through the understanding of good, or what is the same, through truth, are introduced into the will of good, or what is the same, into good; not however into anything of the will of good from themselves, for with them all the will of good has been lost (see n. 895, 927, 2124); but into a new will which they receive from the the Lord, (n. 863, 875, 1023, 1043, 1044); and when they have received this will they are then called specifically the redeemed.
