Seven, as in Revelation 15:1, signifies everything in an universal sense. The number 'seven' was considered holy, as is well known, because of the six days of creation, and the seventh, which is the celestial self, where peace, rest, and the Sabbath is. The number seven occurs so frequently in the rites of the Jewish church and is held holy everywhere.

So times were divided into seven, longer and shorter intervals, and were called weeks, like the great intervals of times till the coming of the Messiah, in Daniel 9:24-25. The time of seven years is called 'a week' by Laban and Jacob, as in Genesis 29:27-28. So wherever the number seven occurs, it is considered holy and sacred, as in Psalm 119:164, and in Isaiah 30:26.

As the periods of a person's regeneration are distinguished into six, prior to the seventh, or the celestial self, so the times of vastation are also distinguished, until nothing celestial is left. This was represented by the many captivities of the Jews, and by the last Babylonian captivity, which lasted seven decades, or seventy years. This was also represented by Nebuchadnezzar, in Daniel 4:16, 22, 29. It also refers to the vastation of the end times, in Revelation 15:1, 7-8. They should 'tread the holy city under foot, forty and two months, or six times seven,' as in Revelation 11:2 and Revelation 5:1. So the severity and increments of punishment were expressed by the number seven, as in Leviticus 26:18, 21, 24, 28 and Psalm 79:12.

3620. 'I loathe my life on account of the daughters of Heth' means a connection with natural truth from some other source. This is clear from the meaning of 'loathing one's life' as no connection, that is to say, of the truth of the natural with the truth of the rational - for when these two are not connected to each other it seems to the rational as though its own life were no life, as may be seen from what has been stated above in 3493; and from the meaning of 'the daughters of Heth' as affections for truth from a non-genuine source, in this case affections for natural truth, since Rebekah said this to Jacob who, as shown above, represents natural truth. For 'the daughters' means affections, see 2362, and 'Heth' or Hittite truth from a non-genuine source, 3470. From these meanings it is clear that 'I loathe my life on account of the daughters of Heth' means that there should not be any connection with the natural through truth which does not come from a genuine source, thus that no connection with natural truth from some other source should exist. The connection with natural truth is dealt with later on where Jacob's stay with Laban is the subject - that is to say, when truths from a common stem have been joined on to it. Since the truths which 'the daughters of Heth' represent did not come from that common stem no connection of them with natural truth was possible, because they were dissimilar and did not accord with it. Actually the spiritual Church among gentiles, 2913, 2956, is represented by 'the sons of Heth', but as the Word does not exist in that Church the Word is not the source of its truths.
