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.

5353. 'And all my father's house' means the removal of hereditary evils. This is clear from the meaning of 'father's house' here as hereditary evils. In the internal sense 'house' means a person, more particularly his mind, either his rational mind or his natural mind. But specifically the will part there is meant, consequently good or evil since either of these can exist as an attribute of the will, see 710, 2233, 2234, 3128, 4973, 4982, 5023. This being so, 'father's house' here means hereditary evils. The essential nature meant by 'Manasseh' is contained in these words and in those immediately before them. In the original language Manasseh means forgetfulness, and so in the internal sense a removal is meant. That is to say, a removal of evils, both those of one's own doing and those which are hereditary; for once those evils have been removed a new area of will arises. This new will comes into being through an inflow of good from the Lord. Such an inflow of good from the Lord takes place constantly with a person, but evils exist there - both those of his own doing and those which he has inherited - which hinder and stand in the way of the reception of it. But once these have been removed a new area of will comes into being. Its coming into being at this time is clearly evident with those who suffer misfortunes, tribulations, or illnesses. During these experiences self-love and love of the world from which all evils spring are removed, and then a person entertains thoughts about God and about the neighbour that are good, and also desires his neighbour's welfare. It is similar with temptations, which are spiritual forms of distress and therefore inward experiences of tribulation and of despair. These experiences serve primarily to remove evils, and after these have been removed heavenly good from the Lord enters in, from which a new area of will is formed in the natural, which in the representative sense is 'Manasseh'.
