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.

2276. 'Perhaps thirty will be found [there]' means some existence of conflict. This is clear from the meaning of the number 'thirty'. The reason 'thirty' means some existence of conflict, thus a small amount of conflict, is that this number is the product of 'five', meaning that which is small, times 'six', meaning toil or conflict, as shown in Volume One, in 649, 720, 737, 900, 1709.

[2] Hence also that number, wherever one reads it in the Word, means something relatively small, as in Zechariah,

I said to them, If it is good in your eyes, give me my wages; and if not, withhold them. And they weighed out my wages, thirty pieces of silver. And Jehovah said to me, Throw it to the potter, the magnificent price I was valued at among them. And I took the thirty pieces of silver and threw it into the house of Jehovah, to the potter. Zechariah 11:12-13.

This stands for how small a value those people placed on the Lord's merit, and on redemption and salvation from Him. 'The poster' stands for reformation and regeneration.

[3] This explains the reference to the same thirty pieces of silver in Matthew,

They took the thirty pieces of silver, the price set on him whom they had bought from the children of Israel, and gave them for the potter's field, as the Lord commanded me. Matthew 27:9-10.

From these words it is quite clear that 'thirty' here stands for the small price set on him. A slave, who was not considered to be worth much, was valued at thirty shekels, as is clear in Moses,

If the ox gores a slave or a servant-girl, the owner shall give to his master thirty shekels of silver; and the ox shall be stoned. Exodus 21:32.

How little a slave was considered to be worth is clear from verses 20-21, of that same chapter. In the internal sense 'a slave' stands for toil.

[4] The reason Levites were called upon for ministerial duty - which is described as one 'coming to perform military service and to do the work in the tent [of meeting] - from thirty up to fifty years of age', Numbers 4:3, 23, 30, 35, 39, 43, was that 'thirty' means those who were beginners, thus those who as yet could perform little of what was meant in the spiritual sense by 'military service'.

[5] There are other places in the Word besides these where 'thirty' is mentioned, such as in the requirement that with a young bull a minchah of three tenths [of fine flour] was to be offered by them, Numbers 15:9. Such was required because the sacrifice of an ox represented natural good, as shown above in 2180, and natural good is small in comparison with spiritual good, which was represented by the sacrifice of a ram, and smaller still in comparison with celestial good, which was represented by the sacrifice of a lamb, with which sacrifices a different number of tenths to the minchah were required, as is clear in verses 4-6 of that chapter, and also in Numbers 28:12-13, 20-21, 28-29; 29:3-4, 9-10, 14-15. These differing numbers of tenths, or proportions, would never have been commanded if they had not embodied heavenly arcana within them.

[6] 'Thirty' again stands for that which is small in Mark,

The seed which fell into good ground yielded fruit, growing up and increasing. One bore thirty-fold, and another sixty, and another a hundred. Mark 4:8.

'Thirty' stands for a small yield and for that which has laboured to only a small extent. Those numbers would not have been specified unless they had embodied the things meant by them.
