8858. A person's whole character is determined by the nature of whatever dominates his life; this is what marks him off from others. His heaven is formed in accordance with it if he is good, or his hell if he is bad. For it constitutes his true will and so the true being of his life, which is unchangeable after death. From all this one may see what the life is like in a person who has been regenerated, and what it is like in one who has not been regenerated.

8886. 'The sabbath day' in the highest sense means the union of the Lord's Divine [Itself] and His Divine Human; in the internal sense it means the Divine Human joined to the heavens, and so means heaven and consequently the marriage of goodness and truth there. This is clear from what has been shown already in 8495. Since such things are meant by 'the sabbath', therefore in the representative Church it was most holy. It was that which was to be perpetually in the thoughts, that is, that which was to compose a heavenly life; for what a person thinks perpetually, that is, what reigns universally, composes his life, see 8853 8858, 8865, 8885. The Israelite nation had no thought, it is true, of the union of the Lord's Divine and His Divine Human, or of His union with heaven, or of goodness and truth joined together in heaven, which were meant by 'the sabbath', since they were concerned altogether with external things and not with anything internal. Yet they were commanded to hold the sabbath most holy, in order that Divine and heavenly realities might be represented in heaven. The situation as it was with them is evident from what has been shown already regarding that nation, and regarding a representative of the Church among them, in 3147, 3479, 3480, 3881 (end), 4208, 4281, 4288, 4289, 4293, 4307, 4444, 4580, 4680, 4825, 4844, 4847, 4899, 4912, 6304, 6306, 7048, 7051, 8301 (end).

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'.
