7918. 'And you shall take a bunch of hyssop' means the outward means by which purification is effected. This is clear from the meaning of 'hyssop' as outward truth, the means by which purification is effected, dealt with below. It says that they were to take a bunch of hyssop because 'a bunch' is used to refer to truths and the arrangement of them, 5530, 5881, 7408. The reason why 'hyssop' means outward truth, the means of purification, is that all spiritual purification is effected by means of truths. For the earthly and worldly types of love from which a person has to be purified are not recognized except by means of truths. When these truths are instilled by the Lord a horror of those types of love, as of things unclean and damnable, is also at the same time instilled. The effect this horror has is that when something similar enters the person's thinking the feeling of horror returns, producing a loathing of those types of love. That is how a person is purified by truths, which serve as outward means. This was the reason why it was laid down that knives or 'small swords' made of flint should be used when circumcision took place, 'small swords' or knives made of flint being the truths of faith by means of which purification is effected, see 2799, 7044, and 'circumcision purification from filthy types of love, 2039, 2632, 3412, 3413, 4461, 7045.

[2] Since 'hyssop' had that meaning it was used in cleansings, which in the internal sense meant purifications from falsities and evils, as in the cleansing of leprosy in Moses,

The priest shall take for cleansing a leper two living clean birds, and cedarwood, and scarlet, and hyssop; and he shall dip them in the blood of the slaughtered bird, and sprinkle over the one to be cleansed. Leviticus 14:4-7.

Hyssop was likewise used in the cleansing of the house, if leprosy was in it, Leviticus 14:49-51. The preparation of the water of separation by which cleansings were accomplished also involved the use of cedarwood and hyssop, Numbers 19:6, 18. 'Cedarwood' meant inward spiritual truth, whereas 'hyssop' meant outward [spiritual] truth. Thus 'cedarwood' is the means effecting purification more internally, 'hyssop' the means effecting it more externally. That 'hyssop' is a means of purification is plainly evident in David,

You will purge me with hyssop and I shall become clean; You will wash me and I shall be made whiter than snow. Psalms 51:7.

'Purging with hyssop and becoming clean' stands for external purification, 'washing and being made whiter than snow' for internal purification, 'snow' and 'whiteness' having reference to truth, 3301, 3993, 4007, 5319. 'Hyssop' means a very low kind of truth and 'cedar' a superior kind of truth, as is evident from the following words in the first Book of Kings, Solomon spoke about trees, from the cedar which is in Lebanon even to the hyssop which comes out of the wall. 1 Kings 4:33.

Here 'the cedar' stands for the internal kind of truth and 'hyssop' for the external kind of truth that belong to intelligence.

3412. 'All the wells which his father's servants had dug in the days of Abraham his father, the Philistines stopped them up' means that people who possessed knowledge of cognitions did not wish to know interior truths that came from the Divine and so effaced them. This is clear from the meaning of 'wells' as truths, dealt with in 2702, 3096, here interior truths coming from the Divine since the wells, which mean truths, are said to have been dug by 'his father's servants in the days of Abraham his father' - 'Abraham' representing the Lord's Divine itself, 2011, 2833, 2836, 3251, 3305 (end); from the meaning of 'stopping up' as not wishing to know and so effacing; and from the representation of 'the Philistines' as people who possess no more than a knowledge of cognitions, dealt with in 1197, 1198.

[2] The subject at this point is the appearances of truth that belong to the lower degree, which are able to exist with those who possess a knowledge of cognitions and whom 'the Philistines' are used to mean here. With regard to the interior truths that come from the Divine and are effaced by those called the Philistines, the position is that in the Ancient Church and after it the name Philistines was used for those who gave little thought to life and very much to doctrine, and who in course of time even rejected matters of life and acknowledged matters of faith - which faith was separated from life - as being the essential element of the Church. As a consequence they attached no importance at all to matters of doctrine concerning charity which in the Ancient Church constituted the all of doctrine, and so they effaced it. Instead they proclaimed matters of doctrine concerning faith and centred the whole of their religion in these. And since in this way they departed from the life of charity, that is, from charity as the sum and substance of life, they more than all others were called 'the uncircumcised'. For by 'the uncircumcised' were meant all in whom charity was not present, no matter how much doctrine they knew, 2049 (end).

[3] Because such people departed from charity they also removed themselves from wisdom and intelligence, for no one can have a wise and intelligent discernment of what truth is unless good, that is, charity, reigns in him. Indeed all truth originates in good and has regard to good, so that anyone who is devoid of good is unable to have an intelligent discernment of truth, and does not even wish to know it. When such people in the next life are far away from heaven, light bright as snow is sometimes seen to be with them. But that light is like the light in wintertime which, being devoid of warmth, is unproductive. This also explains why, when such persons draw near to heaven, their light is converted into utter darkness, and their minds into something akin to that darkness, which is stupidity. From these considerations it may now be seen what is meant by the statement that people who possessed no more than a knowledge of cognitions did not wish to know interior truths that came from the Divine and so effaced them.
