Psalm 121 opens with this much-loved line, 'I will lift up my eyes to the hills, from whence comes my help.' The whole psalm assures us of the Lord's continual help; He helps, holds us safe, keeps us, shades us, and preserves us.

Natural images and sensations are used to describe spiritual ones: our eyes and feet, sleep, shade, hills, sun, and moon. They remind us of the correspondences between the natural and spiritual planes of life, helping to express these higher ideas in familiar words.

Spiritually, our eyes represent our understanding. Hills are high places; we look up to them, and we can see long distances from their summits. When we lift up our eyes to the hills, we're consciously trying to elevate our minds to new levels of understanding. Note that here, we're not told to look up to majestic mountains, since they can sometimes be too far, too remote, from our daily life. We just need to look up to nearby hills, to raise our minds above our normal ways of thinking. In the Bible, hills represent good that comes from charity. That kind of good -- a love towards our neighbours - also turns us toward the Lord, who then can more readily deepen and infill that neighbourliness. (Apocalypse Explained 374[5])

Our feet are in contact with the ground, and they hold us up. They represent our natural life. The 'foot not to be moved' is our life's intention, to be standing firm with the Lord's support. (Heaven and Hell 96, 97)

To say that the Lord never sleeps is to state the obvious, as Divine influx must be perpetual to maintain all things. This an important reminder for us, though, because sometimes we feel that the Lord is not with us. However, the Lord is, in fact, always with us and is actually closer to us at such times. (See True Christian Religion 774)

Next, we see that the Lord's presence is active. He is our keeper and our shade. He continually knows what our state is, and provides and protects accordingly. He even withholds spiritual things from us at times, so that we don't spoil them. (See Arcana Caelestia 59[2], and 959 at the end.)

The word 'shade' gives us a good feeling that the Lord is over us, keeping us safe. It can also mean that we occasionally require shade — that is, less sight and clearness — for our own sake. (See Apocalypse Explained 401[34])

The sun and moon often represent the Lord's love and His truth. In this psalm, though, they are used in the opposite sense. They stand for our evil love of self and the false ideas that reinforce it - and those will harm us - unless we accept the Lord's power to constrain them.

At the end of this psalm the word 'preserve' is used three times to express holiness. The repetition is important. It represents our need for preservation in every conceivable way — from now to eternity - throughout our "going out and coming in" - the changing states in our lives. (See Arcana Caelestia 1050)

3934. 'And Leah said, A troop comes!' in the highest sense means Omnipotence and Omniscience, in the internal sense the good of faith, and in the external sense works. This is clear from the meaning of 'a troop' in this context. The reason 'a troop' in the highest sense means Omnipotence and Omniscience is that the word troop here denotes a large number; and when a large number is used in reference to the Lord's Divine an infinitely large number is meant, and this is nothing else than Omnipotence and Omniscience. But the term omnipotence is rooted in the idea of vastness in dimension, and omniscience in the idea of vastness in number. Omnipotence is also rooted in the idea of infinite good, or what amounts to the same, in Divine love and so in the Divine will, whereas omniscience is rooted in the idea of infinite truth, or what amounts to the same, in Divine intelligence. Why 'troop' in the internal sense means the good of faith is a question of correspondence, for good that is the good of charity corresponds to the Lord's Divine omnipotence, and truth which is the truth of faith to His omniscience.

[2] The reason why 'a troop' in the external sense means works is that these correspond to the good of faith. Indeed works are the product of that good, for the good of faith cannot exist without works, just as thinking what is good and willing it cannot exist without the doing of it. The one is the internal, the other the corresponding external. What is more, so far as works are concerned, if they do not correspond to the good of faith they are not the works of charity, nor are they the works of faith, since they are not the outcome of what should properly be within them, but dead works that have no good or truth within them. But when the external does correspond to the internal, works are either those of charity or of faith. The works of charity are those which flow from charity as their soul, but the works of faith are those which flow from faith. The works of charity are done by one who is regenerate, whereas the works of faith are done by one who is not yet regenerate but is becoming so. The same applies to affections, that is to say, to the affection for good and the affection for truth. The regenerate person does good out of an affection for that good and so from a desire for good, whereas the one who is to be regenerated does good out of an affection for truth, and so from a knowledge of good. (How these affections differ from each other has often been shown already.) From this one may see what is meant by works.

[3] Furthermore the relationship of the good of faith to works is like that of a person's will and consequent thought to his face, which, as is well known, is an image of the mind, that is, of the person's will and consequent thought. If will and thought do not present themselves in the face as their true image then hypocrisy or deceit, not will and thought, are manifested there because that person presents a different face from what he wills and thinks. It is similar with every act of the body in relation to the more internal things of thought and will. The internal side of a person lives within his external by means of act or action. If act or action does not accord with his internal it is a sign either that that act is not the product of his internal but a mere response to custom and habit, or that it is something untrue as in hypocrisy and in deceit. Here again one may see what is meant by works. Consequently anyone who professes faith, more so anyone who professes the good of faith, and yet denies works, and more so if he rejects them, is without faith and still more without charity.

[4] This being the nature of the works of charity and faith, and since nobody has any charity or faith in him unless works are being done, the Word therefore mentions works so many times, as may be seen from the following places: In Jeremiah,

Your eyes have been opened upon all the ways of the sons of man, giving to everyone according to his ways and according to the fruit of his works. Jeremiah 32:19.

In the same prophet,

Turn now every one of you from his evil way, and make your works good. Jeremiah 35:15.

In the same prophet, I will requite them according to their work and according to the work of their hands. Jeremiah 25:14.

In Hosea,

I will visit upon him his ways, and requite him for his works. Hosea 4:9.

In Micah,

The earth will be a desolation over its inhabitants, on account of the fruit of their works. Micah 7:13.

In Zechariah,

Thus said Jehovah Zebaoth, Turn from your evil ways and from your evil works. Jehovah Zebaoth thought to deal with us according to our ways, and according to our works so He dealt with us. Zechariah 1:4, 6.

In John,

Blessed are the dead who die in the Lord from now on. Yes indeed, says the Spirit, that they may rest from labours, for their works follow them. Revelation 14:13.

[5] In the same book,

I saw the dead, small and great, standing before God, and books were opened. And another book was opened, which is the book of life, and the dead were judged by the things written in the books, according to their works. The sea gave up the dead that were in it, and death and hell gave up the dead that were in them. They were judged therefore every one according to their works. Revelation 20:12-13.

In the same book,

Behold, I am coming quickly, My reward with Me, to give to everyone according to his work. Revelation 22:12.

In John the Evangelist,

This is the judgement, that light has come into the world, but men preferred darkness rather than light, for their works were evil. Everyone who performs evil deeds hates the light and does not come to the light lest his works should be exposed. Anyone however who does the truth comes to the light, so that his works may be clearly seen, because they have been wrought in God. John 3:19-21.

In the same gospel,

The world cannot hate you, but it hates Me because I testify of it that their works are evil. John 7:7.

In the same gospel,

Jesus said to the Jews, If you were Abraham's sons you would do the works of Abraham. You do the works of your father. John 8:39, 41.

In the same gospel,

If you know these things, blessed are you if you do them. John 13:17.

[6] In Matthew,

Let your light shine before men, that they may see your good works. He who does and teaches so will be called great in the kingdom of heaven. Matthew 5:16, 19.

In the same gospel,

Not everyone who says to Me, Lord, Lord, will enter the kingdom of heaven but he who does the will of My Father who is in heaven. Many will say to Me on that day, Lord, Lord, did we not prophesy by Your name, and by Your name cast out demons, and do many mighty works in Your name? But then I will confess to them, I do not know you; depart from Me, you workers of iniquity! Matthew 7:21-23.

In Luke,

The householder replying says to them, I do not know where you are from. Then you will begin to say, We ate in your presence and we drank; you taught in our streets. But He will say, I tell you, I do not know where you come from; depart from Me, all you workers of iniquity! Luke 13:25-27.

In Matthew,

Everyone who hears My words and does them I will liken to a wise man. But everyone hearing My words and not doing them will be likened to a foolish man. Matthew 7:24, 26.

In the same gospel,

The Son of Man will come in the glory of His Father together with His angels, and at that time He will repay everyone according to his works. Matthew 16:27.

[7] From all these places it is evident that works are what save a person or what condemn him, good works being those that save, evil those that condemn; for his works contain what he wills. Anyone who wills what is good does what is good, but anyone who does not do what is good, no matter how much he may say that he wills it, does not will it when he does not do it. It is as though he were to say, I will it, yet I don't will it. And because the will itself is contained in works, and charity belongs to the will, and faith to charity, it is evident what kind of will, that is, what kind of charity and faith, is present in someone when he does not do good works, and more so when he does the opposite of these.

[8] In addition it should be recognized that the Lord's kingdom begins in a person in the life that belongs to works, for he is then at the start of regeneration; but once the Lord's kingdom is established in him the kingdom ends in works, and then he is regenerate. Indeed the internal man is in this case present in the external in a corresponding fashion; and since works are done by the external man while charity and faith rooted in charity dwell in the internal man, works are therefore at the same time charity. And as it is in the works of the external man that the life of the internal so presents itself, therefore - when speaking about the Last Judgement in Matthew 25:32-46 - the Lord lists nothing else than works, declaring that those who have done good works will enter into eternal life and those who have done evil into a state of damnation. What has been said also shows the meaning of what one reads about John's lying at Jesus' breast and in His bosom and about His loving him more than the rest, John 13:23, 25; 21:20; for John represented good works, see the Prefaces to Genesis 18, 22. What the works of faith are, which from their appearance may be called the fruits of faith, and what the works of charity are, will in the Lord's Divine mercy be discussed more fully elsewhere.
