2269. 'And He said, I will not destroy it if I find forty-five there' means that mankind would not perish if [goods and truths] could be joined together. This is clear from the meaning of the number 'forty-five' as a joining together. It has been shown already that simple numbers retain their own meaning even when they are multiplied; and so larger numbers have a similar meaning to smaller. So it is with 'forty-five', a number which is the product of five times nine; and because it is the product of five times nine it has the same meaning as five and nine. 'Five' means that which is small, as has been shown already in 649, and 'nine' means conjunction or that which is joined together, 2075; so that the meaning here is, If goods have in some measure been joined to truths. That numbers in the Word mean real things or else states is clear from what has been stated above in 2252 about 'fifty', and also from what has been shown already concerning numbers, in 482, 487, 575, 647, 648, 755, 813, 1963, 1988.

[2] It is because 'five' means that which is small, and 'forty-five' a joining together, that those numbers are used in the way they are in this verse. That is to say, first it is said, 'Perhaps the fifty righteous persons will lack five', which means, If it were something less. Then it is said, 'Will You for five destroy the whole city?' which means, Will they perish for the small amount that is lacking? But after that, because five means a small amount, the number five is not used again but it is said, 'I will not destroy it if I find forty-five there', which means that they would not perish if [goods and truths] could be joined together. And a further reason why the expression 'forty-five' is used, and not 'if the fifty are lacking five', is that 'five' not only means that which is small, as shown in 649, but also severance, as has also been shown in Volume One, in 1686. Consequently so that a joining together might be meant and not a severance, this number, that is to say, forty-five is used, for forty-five means some joining together, as stated above. Thus in a very beautiful way every detail follows in its particular sequence in the internal sense.

[3] As regards good and truth when joined together, this is an arcanum that cannot be described in such a way that the ordinary mind is able to grasp it. Let merely a brief explanation be given here. The more genuine and pure truth is, the better is good from the Lord able to be accommodated to it as the recipient vessel; but the less genuine and pure truth is, the less is good from the Lord able to be accommodated. For they must each answer to the other; and to the extent that they do, they are joined together. Goods cannot possibly be received into falsities, nor evils into truths as their recipient vessels, for they are by nature and disposition contrary. The one rejects the other as its very enemy; indeed if they tried to join together, each of them would throw up - good would throw up evil as though it were poison, and evil would throw up good as though it were something that induces vomiting. Such enmity between evil and good has been provided by the Lord to prevent the possibility of their being mixed together, for if they were so mixed a person would perish. Those who are deceivers and hypocrites come near to having the two joined together in them; yet even in their case the Lord takes care to prevent them becoming joined together. This is the reason why in the next life deceivers and hypocrites suffer more dreadfully than all others.

395. 'Anyone killing Cain, vengeance will be taken on him sevenfold' means that to violate faith thus separated was utterly forbidden. This is clear from the meaning of 'Cain' as separated faith, and from the meaning of 'seven' as utterly inviolable. As is well known, the number seven was considered holy on account of the six days of creation and of the seventh, which is the celestial man in whom peace, rest, and the Sabbath exist. This is the reason why the number seven occurs so many times in the religious ceremonies of the Jewish Church, in every instance standing for that which is holy. It is also the reason why periods of time, long as well as short, were divided into seven, and were called weeks, as in the case of the long time intervals leading up to the time when the Messiah was to come, Daniel 9:24-25. A period of seven years is also called a week by Laban and Jacob, Genesis 29:27-28. Consequently wherever the number seven occurs it stands either for something holy or else for something utterly inviolable, as in David,

Seven times in the day I praise You. Psalms 119:164.

In Isaiah,

The light of the moon will be as the light of the sun, and the light of the sun will be sevenfold, as the light of seven days. Isaiah 30:26.

Here 'the sun' is love, and 'the moon' faith deriving from love, a faith which is to be as love.

[2] Just as the periods of man's regeneration divide into six before he reaches the seventh, which is the celestial man, so also do the periods of vastation even until nothing celestial is left. This was represented by the many captivities of the Jews, and by the last of them, the Babylonian, which was a captivity of seven decades, that is, seventy years. And it was several times stated that the land had to rest during its Sabbaths. It was also represented by Nebuchadnezzar, of whom it is said in Daniel,

His heart will be changed from man, and the heart of a beast given him until seven times will pass over him. Daniel 4:16, 25, 32.

In reference to the vastation of the last times it is recorded in John,

I saw another sign in heaven, great and wonderful - seven angels holding the seven Revelation 15:1, 6-7.

They will trample over the holy city for forty-two months (that is, six times seven). Revelation 11:2.

In the same book,

I saw a book [written] within and on the back, sealed with seven seals. Revelation 5:1.

Severe and increased penalties were for the same reason expressed by the number seven, as in Moses,

If you will not obey Me in this matter, I will chastise you seven times worse for your sins. Leviticus 26:18, 21, 24, 28.

In David,

Return to our neighbours sevenfold into their bosom. Psalms 79:12.

So then, it is because it was utterly forbidden to violate faith - since it had a use to serve, as has been stated - that the statement is made about 'vengeance being taken sevenfold on him who killed Cain'.
