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.

3509. 'And Rebekah said to Jacob her son - she said' means the Lord's perception from Divine Truth concerning natural truth. This is clear from the representation of 'Rebekah' as the Divine Truth of the Lord's Divine Rational, dealt with in 3012, 3013, 3077; from the meaning of 'saying' as perceiving, dealt with in 1791, 1815, 1819, 1822, 1898, 1919, 2080, 2506, 2515, 2552, 2619; and from the representation of 'Jacob' as the Lord's Natural as regards truth, dealt with in 3305. From this it is evident that 'Rebekah said to Jacob her son' means the Lord's perception from Divine Truth concerning natural truth. For on the one hand the Lord wished to acquire truth from the Divine Good of the Divine Rational, represented by 'Isaac', through the good of the Natural, represented by 'Esau', by means of which truth He would glorify, or make Divine, the Natural. But on the other hand the Lord wished to acquire truth from the Divine Truth of the Divine Rational, represented by 'Rebekah', through the truth of the Natural, represented by 'Jacob', by means of which truth He would glorify, or make Divine, the Rational. But these two wishes of His cannot be grasped unless light is thrown on the subject from what happens with man when being regenerated or made new by the Lord. And even then it cannot be grasped unless one knows the situation with the rational as regards good and as regards truth there. So let this matter be discussed briefly.

[2] The rational mind is distinguished into two separate mental powers, one called the will, the other the understanding. That which goes forth from the will when someone is being regenerated is called good, and that which goes forth from the understanding is called truth. Until a person has been regenerated the will does not act in unison with the understanding. Instead the will desires good whereas the understanding desires truth; and so different is each desire from the other that the effort of the will is perceived to be quite distinct and separate from that of the understanding. This is perceived however only by those who stop to reflect, knowing what the will is and the things that constitute this, and what the understanding is and the things that constitute that. But it is not perceived by those who do not know those things and therefore do not stop to reflect. And there is the added reason that the natural mind is regenerated by way of the rational mind, see 3493, and indeed according to order as follows: The good of the rational does not pass directly into the good of the natural and regenerate it but by way of truth which belongs to the understanding, thus giving the appearance that it enters in from the truth of the rational. These are the matters which this chapter deals with in the internal sense; for 'Isaac' is the rational mind as regards good present in the will, 'Rebekah' as regards truth present in the understanding. 'Esau' is the good of the natural springing from the good of the rational, 'Jacob' the truth of the natural springing from the good of the rational by way of the truth there.

[3] These considerations show the kind of arcana contained in the internal sense of the Word; yet there are very few which can be described in a way intelligible to the human mind. The number of those which are beyond man's comprehension and defy description is unlimited. For the more deeply the Word goes, that is, the more interiorly into heaven, the more unlimited and also the more indescribable do they become not only to man but also to angels of the lower heaven. And when it reaches the inmost heaven the angels there perceive that the arcana are infinite and, being Divine are quite beyond their comprehension. Such is the nature of the Word.
