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.

10005. 'The robe of the ephod' means the middle part of that kingdom. This is clear from the meaning of 'the robe' as the Divine Spiritual emanating indirectly from the Divine Celestial, thus the middle of the spiritual kingdom, dealt with in 9825. The reason why it is called 'the robe of the ephod' is that the robe went with the ephod; it was also kept distinct from the tunic by means of a girdle. For there were two girdles; the first was an overall one for the ephod and robe together, the second was for the tunic alone. This second girdle served to mean that the things of the spiritual kingdom which were represented by the tunic were distinct and separate from those represented by the robe and ephod together. 'A girdle (or belt)' means a common bond which holds more internal things in connection, 9828, and also serves to separate one thing from another, 9944.

[2] The implications of all this are that there are three realities which follow one another in consecutive order. In heaven those three are called celestial, spiritual, and the natural springing from these. That which is celestial is the good of love to the Lord, that which is spiritual is the good of charity towards the neighbour, and that which is natural and springs from them is the good of faith. What is celestial, or the good of love to the Lord, constitutes the inmost or third heaven; what is spiritual, or the good of charity towards the neighbour, constitutes the middle or second heaven; and what is natural springing from these, or the good of faith, constitutes the lowest or first heaven. Since Aaron's garments represented the Lord's spiritual kingdom, 9814, it is evident from things which have been mentioned what the tunic represented, what the robe represented, and what the ephod represented. That is to say, the tunic represented the intermediary that unites the spiritual kingdom to the celestial kingdom, and therefore also it was kept distinct by means of a girdle from the robe and ephod, which represented the spiritual kingdom, internal and external. Regarding the tunic, see 9826, 9942; regarding the robe, 9825; and regarding the ephod, 9824.

[3] Some idea of this matter may also be gained from what has been shown previously regarding the tent of meeting, which represented heaven in which the Lord was present. The inmost part of it, where the ark of the Testimony was, represented the inmost or third heaven; the dwelling-place, which was outside the veil, represented the middle or second heaven; and the court represented the first or lowest heaven. And they in like manner were celestial, spiritual, and the natural springing from these. But the intermediary uniting the inmost and middle heavens was represented by the veil between the holy place and the holy of holies, in the same way as it was by the tunic on Aaron. Regarding the inmost part of the tent where the ark was, see 9485; regarding the dwelling-place which was outside the veil, 9594, 9632; regarding the court, 9741; and regarding the veil, the intermediary uniting the inmost and middle heavens, 9670, 9671.

[4] An even better idea of these things may be acquired from the correspondence of the human being with the heavens; for all the parts of the human being have a correspondence with everything that exists in the heavens, see what has been shown previously at the ends of a number of chapters. The human head corresponds to the inmost or third heaven, where there is celestial good; the breast down to the loins corresponds to the middle or second heaven, where there is spiritual good; and the feet correspond to the lowest or first heaven, where there is natural good. The neck however, by virtue of correspondence, is the intermediary uniting the inmost and middle heavens, 9913, 9914, in the same way as the veil in the tent was. For all representatives on the natural level resemble the human form and have the same meaning as the parts of it which they resemble, 9496. From all this it now becomes clear why the tunic was kept distinct from the robe and ephod by means of a girdle, and also why the robe is called 'the robe of the ephod'.
