737. 'Noah was a son of six hundred years' means his initial state of temptation. This is clear from the fact from here down to Eber in Chapter 11 nothing else is meant by numbers, years of age, or names than real things, as was the case also with the ages and names of all those mentioned in Chapter 5. Here 'six hundred years' means the initial state of temptation. This becomes clear from its prime factors which are ten and six multiplied again by ten. When the same factors are involved it makes no difference whether the number arrived at is large or small. As for ten, this has been shown already at 6:3 to mean remnants, while the meaning of six here as labour and conflict is clear from places throughout the Word. For the situation is this: What has gone before dealt with man's preparation for temptation, that is to say, he was supplied by the Lord with truths of the understanding and with goods of the will. These truths and goods are remnants, but they are not brought forth so as to be acknowledged until man is being regenerated. In the case of those who are being regenerated by means of temptations the remnants existing with any man are for the angels present with him. From these remnants they draw out those things with which they protect him against the evil spirits who activate falsities with him and in this way attack him. It is because remnants are meant by 'ten' and conflict by 'six' that six hundred years are spoken of, a number in which ten and six are the prime factors and which means a state of temptation.

[2] As regards conflict being the particular meaning of 'six', this is clear from Genesis 1, which describes the six days of man's regeneration prior to his becoming celestial. During those six days there was constant conflict, but on the seventh day came rest. Consequently there are six days of labour, and the seventh is the sabbath, a word which means rest. This also is why a Hebrew slave was to serve for six years and in the seventh was to go free, Exodus 21:2; Deuteronomy 15:12; Jeremiah 34:14, and why for six years they were to sow the land and gather in the produce, but in the seventh they were to leave it alone, Exodus 23:10-12. The same applied to a vineyard. It is also the reason why in the seventh year the land was to have a sabbath of rest, a sabbath to Jehovah, Leviticus 25:3-4. Because 'six' means labour and conflict it also means the dispersion of falsity, as in Ezekiel,

Behold, six men coming from the direction of the upper gate, which looks towards the north, every man with a weapon of dispersion in his hand. Ezekiel 9:2.

And in the same prophet, against Gog,

I will cause you to turn about, and I will split you into six, and cause you to come up from the uttermost parts of the north. Ezekiel 39:2.

Here 'six' and 'splitting into six' stand for dispersion, 'the north' for falsities, and 'Gog' for people who seize on doctrinal matters based on things of an external nature with which they destroy internal worship. From Job,

He will deliver you in six troubles, and in a seventh no evil will touch you. Job 5:19.

This stands for the conflict that constitutes temptations.

[3] 'Six' occurs in other parts of the Word where it does not mean labour, conflict, or the dispersion of falsity, but the holiness of faith. In these instances it is related to twelve, which means faith and all things of faith in their entirety, and to three which means that which is holy. Consequently there is also a genuine derivative meaning to the number six, as in Ezekiel 40:5, where the man's measuring rod with which he measured the holy city of Israel was six cubits long; and in other places. The reason for this derivative is that in the conflict of temptation the holiness of faith is present, and also that six days of labour and conflict look forward to the holy seventh day.

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.
