8815. 'And the voice of a trumpet extremely loud' means a celestial state which was round about. This is clear from the meaning of 'the voice (or sound) of the trumpet' as the truth of celestial good, 'the voice' being truth and 'a trumpet' celestial good, as above in 8802. The reason why a celestial state which was round about is meant is that the Divine in heaven is in the middle or inmost part, that is, the highest part there. But heaven as occupied by angels lies round about or outside, that is, below; for what is round about is also outside, and what is outside is also below. God's truth itself in heaven is meant by 'voices and lightnings'; but celestial or angelic truth linked to the Divine, which is the truth below or round about, is meant by 'the voice of a trumpet'. Similarly in Zechariah,

Jehovah will appear over them, and His arrow will go forth like lightning; and the Lord Jehovih will sound a blast on the trumpet, and move forward in storms of the south. Zechariah 9:14.

And in David,

God has gone up with a blast, Jehovah with the voice of a trumpet. Psalms 47:5

'A blast' stands for the truth of spiritual good, 'the voice of a trumpet' for the truth of celestial good.

[2] Divine Truth passing through heaven is also meant by the trumpets on which the angels blasted in Revelation 8:2, 6-8, 12-13; 9:14. God's truth from heaven was represented too by the seven trumpets on which the seven priests blasted before the Ark or in front of Jehovah when the walls of the city of Jericho fell down, Joshua 6; and also by the trumpets with which the three hundred men accompanying Gideon made a noise around the camp of Midian, Amalek, and the Sons of the East, Judges 7. The reason why the trumpets achieved that effect was that they represented God's truth passing through the heavens. This truth is such that it perfects the good but destroys the evil. It perfects the good because they receive Divine Good present within Truth, but it destroys the evil because they do not receive Divine Good present there. 'The walls of Jericho' meant the falsities that defended evils, and 'Midian, Amalek, and the Sons of the East', around whose camp Gideon's three hundred men blasted on their trumpets, meant those immersed in evils and in falsities arising from them

8794. 'And you are to set bounds for the people round about' means not extending into heaven beyond the spiritual spheres of good. This is clear from the meaning of 'setting bounds round about' as the extension of a sphere into heaven to specific limits that are determined by each one's good; and from the representation of the children of Israel, to whom 'the people' refers here, as those governed by spiritual good in which truth is to be implanted. For this state of the good of those belonging to the spiritual Church is described in the present chapter and in those that follow it, 8753. So it is that 'you are to set bounds for the people round about' means extension into heaven no further than to the spiritual spheres of good.

[2] No one can know except from revelation what to understand by extension into heaven as far as the spiritual spheres of good. The situation is this: Any good imparted to a person through regeneration by the Lord extends itself to communities in heaven. The amount and the nature of this extension varies with each person; it varies in amount as it advances towards more distant boundaries in heaven, and in nature as it shifts more towards the internal parts of heaven or more towards the external parts. The actual good residing with a person flows in from the Lord by way of the communities of heaven that are round about; good that does not flow in by way of those communities is not possible. The communities of heaven exist round about, closely joined together without a break; not a break between them appears anywhere. It is the same with every single thing that is connected with good and constitutes its essential nature. Therefore when a person is being regenerated his enrichment in good is nothing other than being introduced into angelic communities, and in this way being joined to them. See also 4067, 4073, 4077, 6598-6613

[3] This has also been demonstrated to me quite a number of times by actual experience. Sometimes contact with certain communities has been withdrawn from me, and then the amount and the nature of life that remained were determined by the amount and nature of extension into the communities that were left. And when more communities were taken away, my life suffered and began seemingly to be snuffed out. Every angel, spirit, and man has a spiritual sphere, and its nature is determined by its extension into different communities. It extends not into the actual communities, but into the spheres emanating from their good. These matters are arcana that are unknown to anyone in the world but are very well known indeed in the next life. The reason why they are unknown to anyone in the world is that a person at the present day believes that he has life in himself, and consequently that he lives without association with spirits and angels, and so without being linked to heaven. But in this he is altogether mistaken; for all the life a person has comes from the Lord by way of communities [in the spiritual world].

[4] In addition it should be recognized that the life emanating from those belonging to the spiritual Church reaches as far as the angelic spheres in the second heaven, called the spiritual heaven, but not as far as the third heaven, where those who are celestial are. The reason for this is that a member of the spiritual Church cannot receive the Divine as He exists in the inmost or third heaven where those who are celestial are, except in so general a way that he does not even notice it. And the reason for this is that those who are spiritual cannot reach even the outer doorstep of the good governing those who are celestial, 2718, 3833, 6500, 8521. All this shows what should be understood by not extending into heaven beyond the spiritual spheres of good, meant by the injunction 'you are to set bounds for the people round about', and also what should be understood by the words that follow it.

[5] It should also be recognized that just as those governed by good have an extension into angelic communities according to the nature and amount of their good, so those ruled by evil have an extension into hellish communities according to the nature and amount of their evil. And in addition to this, everyone in the next life comes among those with whom he had been in contact during his lifetime. His ruling love determines this; for that love is what constitutes the sphere emanating from each person's life, and extends as far as the nature and amount of it determine.
