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.

4564. 'And was buried below Bethel under an oak' means cast away for ever. This is clear from the meaning of 'being buried' as being cast away, for that which is buried is cast away; and from the meaning of 'under an oak' as for ever, dealt with above in 4552. 'Below Bethel' means outside the natural, for that which is said to be beneath or below is in the internal sense outside, 2148; 'Bethel' is the Divine Natural 4089, 4539.

[2] The implication of this is that with a person who is being regenerated, neither hereditary evil nor that of his own doing is removed in such a way as to disappear or be eliminated, but is merely separated and through the rearrangement effected by the Lord is cast away to the most outlying parts, 4551, 4552. It accordingly remains with that person, and does so for ever, but he is withheld from evil by the Lord and maintained in good. When this happens it seems as though evils have been cast away and the person has been purified from them or, as it is said, made righteous. All the angels of heaven confess that in their case, insofar as anything originates in themselves it is entirely evil and consequently false, but insofar as it originates in the Lord it is good and consequently true.

[3] People who have adopted any other notion concerning this matter, and who from the teaching they received while living in the world have become convinced that they have been made righteous and are in that case without sins, and so are holy, are taken back to the state where their evils reigned - both those of their own doing and those received through heredity. They are then kept in that state until they know from personal experience that of themselves they are nothing but evil and the good which had seemed to them to be their own came from the Lord, and that therefore it was not theirs but the Lord's. This is the situation with angels, as it is with the regenerate among men.

[4] But in the Lord's case it was different. He entirely removed, cast out, and cast away from Himself all hereditary evil from His mother, for being conceived from Jehovah He had no evil by heredity from His Father, only from His Mother. This is the difference; and this is what is meant by the Lord's being made Righteousness, the Holy itself, and the Divine.
