In chapter 4 of the Book of Amos, verses 1-3 are talking about people who pervert the truths of the church. They will fall into falsities in outermost things.

In the Bible, fish represent "lower" things than mammals, so we can interpret the fishhooks in verse 2 as meaning being caught and held fast in natural or lower things.

Verses 4-6 are about acts of worship such as tithes and sacrifices. These look similar to genuine worship, but are only external sorts of things. We can tell because ‘teeth’ (in verse 6) represent ultimates or outermost things (see Secrets of Heaven 6380). It follows that “cleanness of teeth” would mean outermost things that look good but only imitate genuine worship. The Lord exhorts, “Yet you have not returned to me.”

Verses 7-8. Some things true will remain, when where there are too many false ideas, the truths don't get through. This can be seen where the Lord says, “I made it rain on one city; I withheld rain from another city... where it did not rain the part withered.” Again the Lord exhorts, “Yet you have not returned to me.”

Verse 9. Afterward all things of the church are falsified, shown by blight attacking the gardens, vineyards, fig tree and olive trees. The last three represent spiritual, natural and celestial things, or all the things of spiritual life. “Yet you have not returned to me,” says the Lord.

Verses 10-11. The Lord explains the devastating things he allowed to happen: plague in Egypt, death of young men by swords, stench in the camps, Sodom and Gomorrah. This is because they are profaned by sensual knowledges. Profanation means the mixing of good and evil together. (See Secrets of Heaven 1001[2]).

This extends to all things of the church, with the church being the Lord’s kingdom on earth (Secrets of Heaven 768[3]).

With profanation “as soon as any idea of what is holy arises, the idea of what is profane joins immediately to it,” (Secrets of Heaven 301).

Now there is hardly anything left. “Yet you have not returned to Me,” says the Lord again.

Verses 12-13: Because people adamantly remain in their profane ways, they are warned, “Prepare to meet your God!”. This is the God powerful and mighty, “who forms mountains, and creates the wind,” and even more close to home, “Who declares to man what his thought is.” As intimately a knowing as that is, the Lord’s love for all humanity is contained in His exhortations for them to turn themselves to Him.

See, for example, Luke 6:44-45, and True Christian Religion 373.

6516. 'In my grave which I dug for myself in the land of Canaan, there you are to bury me' means that it - the Church - was to be restored to life where the previous one had existed. This is clear from the meaning of 'a grave' and 'burying' as restoring to life, dealt with in 5551; and from the meaning of 'the land of Canaan' as the Lord's kingdom and the Church, dealt with in 1413, 1437, 1607, 1866, 3038, 3481, 3705, 4240, 4447. The reason Jacob wished to be buried in the land of Canaan, where Abraham and Isaac had been buried, and not in any other place was that his descendants were going to possess that land, and so he would be lying among his own people. But in the internal sense not this but something else is meant, namely regeneration and resurrection, because these are what the Church resides in. For 'burial' means in the internal sense regeneration and resurrection, 2916, 1917, 4621, 5551. While 'the land of Canaan' means the Church, as is evident from the places referred to above in the present paragraph, and Abraham, Isaac, and Jacob represent the Lord as regards the Divine itself and the Divine Human, and in the relative sense the Lord's kingdom as regards the internal aspect and the external aspect of it, 1965, 1989, 2011, 3245, 3305 (end), 4615, 6098, 6185, 6276. This then is what is meant in the internal sense by the burial of them in that land; and it explains why among Jews who believe in resurrection the conviction continues to exist that even though they have been buried in some other place they will nevertheless rise again in the land of Canaan.

[2] The reason why it is said that the Church was to be restored to life in the place where the previous one had existed is that the Lord's Church had existed in that land since most ancient times, see 3686, 4447, 4454, 4516, 4517, 5136. It also explains why Abraham was told to go there and why the descendants of Jacob were led into it. And the reason for all this was not that the land was holier than all others but that since most ancient times all the locations there, both provinces and cities as well as mountains and rivers, had been representative of such things as belonged to the Lord's kingdom; and the actual names conferred on those locations implied such things. For every particular name supplied from heaven to a place or person implies some celestial or spiritual reality; and when the name has been supplied from heaven, that reality is perceived by them there. The Most Ancient Church too, which was celestial and was in contact with heaven, was one that used to confer names. The reason therefore why the Church was to exist again in that land was that a Word was going to be given in which every detail would be representative of and would mean some spiritual or celestial reality, and that Word would accordingly be understood in heaven no less than on earth. But this could not possibly have been accomplished unless also the names of places and persons had had spiritual meanings. This is the reason why the descendants of Jacob were led into that land, why prophets were raised up there through whom the Word was written, and therefore why a representative of the Church was established among Jacob's descendants. From all this one may see the reason for the statement that the Church was to be restored to life where the previous one had existed.

[3] The fact that names in the Word mean spiritual things may be seen in 1224, 1264, 1876, 1888, 4442, 5225, as well as in the multitude of places where explanations are given of what their meanings are. But the fact that in heaven they perceive what the meanings are of names used in the Word, and that they do this without prior instruction, is an arcanum unknown as yet to anyone and must therefore be described. When the Word is read the Lord comes in and teaches; also - and this is one of the marvels in the spiritual world - writings exist, which I have frequently seen and been able to read yet not understand. But good spirits and angels understand them perfectly well because those writings accord with the universal language they speak. I have been led to know that individual words used there, even individual letters, hold within themselves the kinds of things that belong to that world, thus spiritual things, and that these are perceived there from the breath that is used, and from the affection resulting from the uttering of those words, thus from the varying smooth or rough delivery of them. But it is probable that hardly anyone will believe this. This arcanum has been disclosed so that people may know that those in heaven perceive instantly what the meanings are of names used in the Word, because those names are registered in heaven.
