9550. 'Solid shall the lampstand be made' means that all of it must spring from good. This is clear from the meaning of 'solid' as the entire whole, consequently as the necessity for all of it to spring from good, which is meant by 'gold'. For the whole of the spiritual, meant by 'the lampstand' since it serves to shed light, arises from the celestial and is also kept in constant being by means of it, even as all truth springs from good. If you take away good, truth is instantly wiped out; for the soul of truth is good. It is like an affection belonging to love and its link to thought. If that affection is taken away, the thought is immediately wiped out; for the affection is the actual life or the soul of the thought. Every affection belonging to love has connection with good, and every thought springing from it has connection with truth. The truth which springs from good is called spiritual, and the good from which the truth springs is called celestial.

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.
