Psalm 38 is an interesting one, because its overall theme is of feeling chastened by the Lord. To be ‘chastened’ means to be corrected by going through suffering. The speaker does not rail against God at all; he understands the purpose God must have in needing to correct him and bring him to task. He declares his own wrongness and his wretchedness. His trust in the Lord is sure and strong, and we get the sense that he fully understands that all this is the Lord’s way of salvation for him. The opening and closing verses talk about the Lord urgently and with conviction.

Spiritually, this psalm describes our need to understand and accept our frail and broken human nature. By "accepting" I don't mean being satisfied with our spiritual state, or resigned to it. We need even to be practising repentance daily in some way (see The New Jerusalem 163). Repentance involves examining ourselves and seeing our true state and bringing ourselves to the Lord for his aid, protection and illumination. This is an ongoing need. We keep learning to understand more about how the Lord works with us and how we are to manage our spiritual states.

This psalm also describes the Lord’s own deep temptations during his human life. Verses 1 to 10 describe these temptations, such as, “My wounds are foul and festering because of my foolishness” (verse 5). Verses 11 and 12 speak of even those ‘friends’ and ‘companions’ who love good and truth turning from the Lord, wanting his death. Verses 13 and 14 tell us that the Lord bears all this with patience, and verses 15 to 22 (and also verse 9) are about the Lord’s confidence that the hells will not prevail against him.

The psalm begins with the plea not to be punished by the Lord’s anger or his wrath. During our temptations, this is the appearance, yet it is essential that we appreciate that the Lord never punishes but only seek to save us. The Lord’s ‘anger’ is his resolve to free us from evils; the Lord’s ‘wrath’ is his determination to free us from false beliefs. (Arcana Caelestia 3614)

‘Arrows pierce me deeply’ means the way in which the Lord’s truths penetrate our spirit, speaking to it and challenging it and often bringing us pain. (Arcana Caelestia 2686).

The Lord’s hand ‘presses me down’ stands for the Lord’s opposition to our evils (not to us!) because ‘hands’ represent Divine power. (Heaven and Hell 232).

The speaker uses the various organs in our body to describe our various spiritual ailments: flesh, bones, head, wounds, loins, heart and eyes… quite a comprehensive list. ‘Bones’ stand for the truths which support our spiritual frame; ‘loins’ stand for our spiritual loves but also our passions. Each of these organs is defective in the psalm. (Arcana Caelestia 8364)

Verses 11 and 12 talk about the aloofness of friends and relatives, and the deceit of those who want to destroy. Spiritually, this describes the influences that come into our minds during temptation. The heavenly influence seems far off and unable to help us, the hellish influences seem close and condemning. (Arcana Caelestia 9348)

This is immediately followed by words talking about not hearing and not speaking out. In a general way, spiritually, this stands for us not being swayed by the influences – the “voices” – which come into our thought, whatever kind these may be, because we cannot determine their true quality. In a more specific way, it means the refusal to judge and condemn others for their actions. This would be most true of the Lord. (Apocalypse Explained 409)

Then comes the real reason and purpose for us during every temptation, that we are to put our trust in the Lord who hears and knows everything. Only this can be our full confidence.

The final two verses of the psalm are worded as a prayerful request to not be forsaken and to be helped by the Lord. The meaning is right on the surface here. We need to ask the Lord for help, and we also need to understand that the Lord never forsakes us or is unwilling to help.

9410. 'He did not lay a hand' means that truth in its power is not present there. This is clear from the meaning of 'hand' as the power which comes through truth. For the meaning of 'hand' as power, see 878, 3091, 3387, 4931-4937, 5327, 5328, 5544, 6947, 7011, 7188, 7189, 7518, 7673, 8050, 8153, 8281, 9025, 9133; for its coming through truth, 3091, 3503, 6344, 6423, 8304; and for the fact that truth derives all its power from good, that is, from the Lord through good, 6948, 8200, 9327. From all this it is evident that 'He did not lay a hand towards the children of Israel who had been set apart' means that truth in its power is not present with those restricted to the outward sense of the Word, separated from the inward. The reason why truth is not present with them in its power is that they are separated from heaven and so from the Lord; for the Word joins a person to heaven, and through heaven to the Lord, because all the things constituting the sense of the letter of the Word correspond to the spiritual and celestial realities which exist with angels. There is no connection with the angels if the Word is understood according to the letter alone and not at the same time according to some teaching of the Church on the inner level of the Word.

[2] Take for example the Lord's words to Peter,

You are Peter, and on this rock I will build My Church, and the gates of hell will not prevail against it. And I will give you the keys of the kingdom of heaven; and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven. Matthew 16:18-19.

In like manner to the disciples,

Truly I say to you, Whatever you bind on earth will be bound in heaven; and whatever you loose on earth will be loosed in heaven. Matthew 18:18.

Those who are restricted to the outward sense of the Word, separated from the inward, thus those who are separated from the true teachings of the Church, convince themselves that such power was given to Peter by the Lord, and also to the rest of the Lord's disciples. This conviction leads to the hellish heresy that certain people possess the power to let into or shut out of heaven whomsoever they please, when in fact according to the true teachings of the Church, which lie on the inward level of the Word, the Lord alone has that power. Those therefore who know the outward sense of the Word and at the same time its inward sense understand that these things spoken by the Lord had regard to faith and the truths of faith which are received from the Lord, and that such faith received from the Lord possesses that power, thus the Lord Himself, and not at all any mere human being.

[3] The truth of this may be recognized from the representation of Peter and of the twelve disciples, also from the meaning of 'rock', and from the meaning of 'keys' as well. Peter represented faith, see Prefaces to Genesis 18, 22, also 3750, 4738, 6000, 6073 (end); the Lord's twelve disciples, like the twelve tribes of Israel, represented all aspects of faith and love, 3488, 3858, 6397; 'rock' means the Lord in respect of faith, and so faith which is received from the Lord, 8581; and 'keys' means power, as is clear from places in the Word where keys are mentioned, such as in John,

I am the First and the Last, He who lives; and I was dead, but behold, I am alive for ever and ever, and have the keys of hell and of death. Revelation 1:17-18.

In the same book,

These things says the One who is Holy, the One who is True, He who has the key of David, He who opens in order that no one may close, and closes in order that no one may open ... Revelation 3:7-8.

And in Isaiah,

I will place the key of the house of David on His shoulder, in order that He may open and none shut, and He may shut and none open. Isaiah 22:22.

In these places it is evident that 'key' means power and that the Lord alone possesses it.

[4] From all this one can see what those people are like who are restricted to the outward sense of the Word, separated from the inward, namely people who are not at all joined to heaven, nor thus to the Lord. This is so with those who explain those words addressed by the Lord to Peter and to the disciples according to their literal meaning, in that they arrogate to themselves the power to save the human race and make themselves the gods of heaven and earth, which they do on account of their insane self-love and love of the world. Anyone sound in mind may see and appreciate that a mere human being cannot absolve any sin at all, because no sin is absolved except through the development of a new life, that is, through being regenerated by the Lord. Regeneration continues right on to the end of a person's life in the world, and after that for evermore, see 8548-8553, 8635-8640, 8742-8747, 8853-8858, 8958-8968.

[5] What truth in its power is must also be stated briefly. In the Word angels are called 'powers'; and it is also well known in the Church that they are such. Yet they are not powers by virtue of anything their own, only by virtue of the Lord; for they are recipients of God's truth which emanates from the Lord. The power they have from the Lord is such that one of them can drive away a thousand of the devil's crew, confine them to the hells, and keep them in check. For God's truth emanating from the Lord fills the heavens and forms them; and if you are willing to believe it, all things were made and created through that truth. The Word which was in the beginning with God and which was God, and through which all things were created and the world was made, spoken of in John 1:1-14, is Divine Truth. Divine Truth is the one true substance from which all things come into being; but this is something few are able to understand, because at the present day the idea which people have of Divine Truth is no different from that of words coming from the lips of one who rules over all, whose orders are carried out according to those words. As for the kind of idea people ought in fact to have of Divine Truth, see 9407 (end). The omnipotence of Divine Truth emanating from the Lord is described in many places in the Word, and especially in John, in the Book of Revelation,

War took place in heaven. Michael and his angels fought against the dragon, and the dragon fought, and his angels, but they did not prevail, nor was their place found any longer in heaven. They conquered him by the blood of the Lamb and by the word of their testimony. Revelation 12:7-8, 11.

'The blood of the Lamb', it is evident, is Divine Truth emanating from the Lord's Divine Human, see 4735, 6978, 7317, 7326, 7850, 9127, 9393, 9395; and 'the word of their testimony' is God's truth which has found acceptance.

[6] People who are restricted to the outward sense of the Word, separated from the inward, that is, those who are separated from the true teachings of the Church, understand these words of prophecy in solely a literal way. That is to say, they take 'blood' to mean blood, thus the Lord's passion, when in fact Divine Truth emanating from the Lord is what is meant in those words by 'blood'. People with the true teachings of the Church are able to know that they are saved not by blood but by hearing God's truth and doing it, thus [that all are saved] who allow the Lord to regenerate them by means of Divine Truth. All who receive enlightenment from the Lord are able to know, understand, see, and perceive this, thus all who are governed by the good of charity and faith are able to do so, since it is they who receive enlightenment. I myself can certainly say that when I read the blood of the Lamb and think of the Lord's blood the angels present with me know no other than that Divine Truth emanating from the Lord is what I read and that that Truth is what I think of. But let simple people hold on to the teaching they have that they are saved by the Lord's blood, so long as they are leading a life in keeping with His Divine Truth; for those who lead such a life receive enlightenment in the next life.
