In Jonah 2:1-10, Jonah is trapped in the belly of the great fish. He prays for salvation, and in the end, after this terrible trial, he is vomited forth onto dry land.

Before a new church -- either a state of good and truth with a group of people, or a new state of good an truth in ourselves - can come into existence, a period of temptation, of struggle, must occur. During this time a remnant of good and truth from prior states, will be preserved. This happens to us. When we really don't want to do something that we know we should do, we get into a state of spiritual temptation. That's what this chapter is about.

In Arcana Coelestia 756, it says: "In Jonah, 'The waters closed around me, even to my soul, the deep surrounded me. Here... 'the waters' and 'the deep' stand for the full extent of temptation.

This chapter also prophesies, or foreshadows, the combats that Jesus Christ would have with the hells, and his most grievous temptations at the time. The “three days and nights during which Jonah was in the bowels of the fish,” signify the entire duration of the combat with the hells.

In the New Testament, in Matthew 12:39-41, there's a reference back to this story:

"No sign will be given to it except the sign of the prophet Jonah. For as Jonah was three days and three nights in the belly of the great fish, so will the Son of Man be three days and three nights in the heart of the earth. The men of Nineveh will stand up at the judgment with this generation and will condemn it, because they repented at the preaching of Jonah. And now One greater than Jonah is here.

For us, then... what? When we've turned away from the Lord, and we're in "the belly of the fish" - in temptations, struggles, combats, and everything looks pretty hopeless - then if we really pray, and seek the Lord's help, he can help us.

Here's a link to an interesting (audio) sermon on this chapter, by Rev. Todd Beiswenger.

7523. 'And there will be on man and on beast' means the products of interior and exterior evil. This is clear from the meaning of 'man' as the affection for good, and in the contrary sense as the desire for evil; and 'beast' is similar in meaning. But when 'man' and 'beast' are mentioned together, 'man means interior affection or desire and 'beast' exterior; regarding both, see 7424. Interior good or else interior evil, which is meant by 'man', is that connected with intentions or ends in view, for intentions or ends in view are at a person's core, whereas exterior good or else exterior evil, which is meant by 'beast', is that connected with thought and consequently, if nothing stands in the way, with action. Exterior good is meant by 'beast' because a person is in respect of his external or natural man no different from a beast; for he is endowed with similar desires and also cravings, as well as appetites and senses. And interior good is meant by 'man because it is in respect of his internal or spiritual man that a person is a human being, on which internal level he is endowed with affections for what is good and true such as exist with the angels in heaven, and because he controls his natural or animal man, which is 'a beast', by means of that internal man. Regarding the meaning of 'beast' as the affection for good and in the contrary sense the desire for evil, see 45, 46, 142, 143, 246, 714, 715, 719, 776, 2179, 2180, 3218, 3519, 5198.

[2] These things are what are meant by 'man and beast' in the following places too: In Jeremiah,

My anger and My wrath have been poured out on this place, on man and on beast. Jeremiah 7:20

In the same prophet,

I will strike the inhabitants of this city, both man and beast; they will die of a great pestilence. Jeremiah 21:6.

In the same prophet,

It will make her land a desolation, so that none may dwell in it; both man and beast have scattered themselves, they have gone away. Jeremiah 50:3.

In Ezekiel,

When a land has sinned against Me by committing great transgression, I will cut off from it man and beast. Ezekiel 14:13, 19, 21.

In the same prophet,

I will stretch out My hand over Edom, and cut off from it man and beast, and make it a waste. Ezekiel 25:13.

In Zephaniah,

I will consume man and beast, I will consume the birds of the air and the fish of the sea, and the stumbling-blocks with the wicked; and I will cut off man from the surface of the earth. Zephaniah 1:3.

[3] 'Man and beast' stands for interior and exterior good in the following places: In Jeremiah,

I have made the earth, man and beast, by My great strength. Jeremiah 27:5.

In the same prophet,

Behold, the days are coming, said Jehovah, in which I will sow the house of Israel and the house of Judah with the seed of man and the seed of beast. Jeremiah 31:17.

In the same prophet,

A desolation will the earth be, so that man and beast are not there. Jeremiah 32:43.

In the same prophet,

In the cities of Judah, and in the streets of Jerusalem, that have been devastated, there is no man and inhabitant, and there is no beast. Jeremiah 33:10; 51:62.

In David,

Your righteousness is like the mountains of God, Your judgements a great deep; You preserve man and beast, O Jehovah. Psalms 36:6.

It was because 'man and beast' meant such things that the firstborn of the Egyptians died, not only of men but also of beasts, Exodus 12:29, and that the firstborn were consecrated [to Jehovah], not only of men but also of beasts, Numbers 18:15, and also that the king of Nineveh, following sacred religious practice, commanded that not only man but also beast should fast and also be clothed in sackcloth, Jonah 3:7-8.
