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.

575. 'The days of man were to be a hundred and twenty years' means that he ought to have remnants of faith. At verses 3, 4 of the previous chapter it was stated that 'days' and 'years' meant periods of time and states, and that the most ancient people meant states and changes in the states of the Church by the numbers which they compounded variously. The exact nature of their computation of things that had to do with the Church is one of those matters that have been lost. Here in like manner numbers of years occur, whose meaning nobody can possibly know unless he knows what is concealed in each of the numbers 1-12, and so on. It is quite apparent that they embody some arcanum or other, for in saying that they would live a hundred and twenty years this verse contradicts those that go before it. Nor subsequently did they live a mere hundred and twenty years, as is clear from what Chapter 11 says about those who lived after the Flood - that Shem lived 500 years after he beget Arpachshad, Arpachshad 407 years after he beget Shelah, Shelah 403 years as well after he beget Eber, and Eber 430 years after he beget Peleg. Chapter 9:28 says that Noah lived 350 years after the Flood; and other examples could be given. What the number 120 embodies however is clear merely from the numbers to and 12, for 120 is the product of 10 times 12. It means remnants of faith. In the Word the number ten has the same meaning as tenths, representing remnants which are preserved by the Lord within the internal man. And since these are the Lord's alone they are holy. The number twelve means faith, that is, all things belonging to faith in their entirety. So this composite number means remnants of faith.
