The 23rd Psalm is one of the best-known and most-loved literary works in the world, and it may well be the best poem ever written. It is also a fine example of the power of figurative language: We read deep things into the vision of ourselves as sheep, led to green pastures and good water by a kind shepherd. It’s empowering to feel the confidence to go fearlessly into the valley of the shadow of death, and to feel the love and caring of a table prepared by the Lord and a cup so full it overflows.

What people don’t know, however, is that this language actually has precise internal meanings, and that when we see them there is an even deeper beauty in the poem. That’s because what it actually describes is the path to heaven, and the fierce desire the Lord has to lead us there.

The first step is to let the Lord be our shepherd – to accept His teaching and His leadership. The green pastures and the still waters represent the things He will teach us for the journey. Then He begins working inside is, setting our spiritual lives in order, so that we desire to do what’s good and to love one another. That’s represented by restoring our souls and leading us in the paths of righteousness.

But we will still face challenges. We still live external lives, out in the world, and we are subject to desires that arise in those externals, in our bodily lives. That’s the valley of the shadow of death. But the rod and staff represent truth from the Lord on both external and internal levels, ideas that can defend us against those desires.

And if we keep following, the Lord will prepare a table for us – a place inside us that he can fill with love (the anointing oil) and wisdom (the overflowing cup). Thus transformed, we can enter heaven, with love for others (“goodness”) and love from the Lord (“mercy”) and can love and be loved to eternity.

One of many beautiful things about this is the fact that it is the Lord who really does all the work. In the whole text, the only action taken by the sheep is walking through the valley of the shadow of death. Other than that, they follow the Lord, trust the Lord, accept the blessings of the Lord. And that is really true! In external states (in the valley) we might seem to be doing the work ourselves, but internally, spiritually, we simply need to give ourselves to the Lord and let Him bless us.

The underlying idea here is that the Lord created us so that He could love us, in loving us wants us to be happy, knows that our greatest happiness will come from being conjoined to Him in heaven, and Himself wants nothing more than to be conjoined to us. So everything He does, in every moment of every day for every person on the face of the planet, is centered on the goal of getting that person to heaven. He wants each and every one of us in heaven more than we are capable of imagining. We just need to cooperate.

314. A Lamb standing, signifies the Lord in respect to the Divine Human. This is evident from the signification of "lamb," as being, in reference to the Lord, Himself in respect to the Divine Human. The Lord in respect to the Divine Human is called a "lamb" because a "lamb" signifies the good of innocence, and the good of innocence is the good itself of heaven proceeding from the Lord; and so far as angels receive this good, so far they are angels. This good reigns with angels that are in the third or inmost heaven; for this reason those in that heaven appear as infants before the eyes of other angels. (What the good of innocence is, and that the angels of heaven are in that good, see in the work on Heaven and Hell, in the chapter treating of The State of Innocence of the Angels of Heaven, n. 276-283, also n. 285, 288, 341, 382.) It is believed in the world that the Lord is called "a Lamb" for the reason that the continual burnt-offering, or what was offered every day, evening and morning, was from lambs, and especially on the Passover days, when a lamb was also eaten; and that the Lord suffered Himself to be sacrificed. Such a reason for His being so called may do for those in the world who do not think beyond the sense of the letter of the Word; but nothing of this kind is perceived in heaven when the term "lamb" is predicated of the Lord; but when "lamb" is mentioned, or is read in the Word, the angels, because they are all in the spiritual sense of the Word, perceive the good of innocence; and when the Lord is so called, they perceive His Divine Human, and at the same time the good of innocence that is from Him. I know that this will with difficulty be believed, but yet it is true.

[2] That "lamb" in the Word signifies the good of innocence, and in reference to the Lord Himself, "lamb" signifies His Divine Human, can be seen from the following passages. In Isaiah:

Behold, the Lord Jehovih cometh in strength. He shall feed His flock like a shepherd; He shall gather the lambs into His arm, and shall carry them in His bosom, and shall gently lead the sucklings (Isaiah 40:10-11).

This treats of the Lord's coming; the "flock that He shall feed as a shepherd," signify those who are in the good of charity; and the "lambs that He shall gather into His arm," signify those who are in love to Him. It is this love that, viewed in itself, is innocence; therefore all who are in it are in the heaven of innocence, which is the third heaven; and as this love is signified by lambs, it is also said, "He shall gently lead the sucklings." "Sucklings" and "infants" in the Word mean those who are in innocence (See in the work on Heaven and Hell 277, 280, 329-345).

[3] In the same:

The wolf shall sojourn with the lamb, and the leopard shall lie down with the kid, the calf and the young lion and the fatling together, and a little boy shall lead them; and the heifer and the bear shall feed, their young ones shall lie down together; the suckling shall play on the hole of the adder, and the weaned child shall put his hand on the basilisk's den (Isaiah 11:6-8).

These things are said of the Lord's coming and of His kingdom, also of those therein who are in the good of innocence, that they shall have nothing to fear from the hells and the evils therefrom, because they are protected by the Lord. The Lord's kingdom is here described by innocences of various kinds, and by their opposites from which they shall be protected; a "lamb" means innocence of the inmost degree, its opposite is the "wolf;" a "kid" means innocence of the second degree, the opposite of which is the "leopard;" a "calf" means innocence of the last degree, the opposite of which is the "young lion." (That "lamb," "ram," or "sheep," and "calf," signify three degrees of innocence, see Arcana Coelestia 10132.) Innocence of the inmost degree is such as belongs to those who are in the third or inmost heaven, and its good is called celestial good; innocence of the second degree is such as belongs to those who are in the second or middle heaven, and its good is called spiritual good; and innocence of the last degree is such as belongs to those who are in the first or the last heaven, and its good is called spiritual-natural good. (That all who are in the heavens are in some good of innocence, see Arcana Coelestia 4797.) Because the goods of innocence are described by the animals above named, it is said further "and a little boy shall lead them," also, "the suckling shall play on the hole of the adder, and the weaned child shall put forth his hand on the basilisk's den." These degrees of innocence are signified also by "boy," "suckling," and "weaned child." (That "boy" has this signification, see Arcana Coelestia 430, 5236; that "suckling," or infant of the first age, and "weaned child," or infant of the second age, have these significations see n. 3183 4563, 5608, 6740, 6745)

[4] Because a "lamb" signifies innocence, or those who are innocent, and a "wolf" those who are against innocence, it is said in like manner in another place in the same prophet:

The wolf and the lamb shall feed together; they shall not do evil in the whole mountain of holiness (Isaiah 65:25);

"the mountain of holiness" is heaven, especially the inmost heaven. Therefore the Lord said to the seventy whom He sent forth:

I send you forth as lambs in the midst of wolves (Luke 10:3).

[5] Because "lambs" signify those who are in the love to the Lord, which love is one with innocence, and because "sheep" signify those who are in love towards the neighbor, which love is charity, the Lord said to Peter:

Simon, son of Jonas, lovest thou Me? He saith unto Him, Yea, Lord; Thou knowest that I love Thee. He saith unto Him, Feed My lambs; and afterwards, Feed My sheep (John 21:15-17).

These things were said to Peter, because by "Peter" truth from good, or faith from charity was meant, and truth from good teaches; "to feed" meaning to teach.

[6] In Ezekiel:

Arabia and all the princes of Kedar, these were the merchants of thy hand, in lambs, rams, and goats (Ezekiel 27:21).

This is said of Tyre, by which those who are in the knowledges of truth and good are meant. "Arabia" and "the princes of Kedar," who are "the merchants of her hand," signify those who are in truths and goods from knowledges; "merchants" signify those who communicate and teach these; "lambs, rams, and goats," signify three degrees of the good of innocence, the same as "lambs, rams, and calves." (That these signify the three degrees of the good of innocence, see Arcana Coelestia 10042, 10132)

[7] In like manner in Moses:

He made him to ride on the high places of the earth, and fed him with the increase of the fields; he made him to suck honey out of the cliff, and oil out of the flint of the rock; butter of the herd and milk of the flock, with the fat of lambs, of the rams of Bashan, and of goats, with the fat of the kidneys of wheat; and thou drinkest the pure blood of the grape (Deuteronomy 32:13-14).

These things are said of the establishment of the Ancient Church, which was the first church after the flood, and all these things describe its various kinds of good; but as scarcely anyone will understand them without explanation, I will briefly explain them. "To ride on the high places of the earth" signifies that the intelligence of those who were of that church was interior; "He fed him with the increase of the fields" signifies that they were instructed in all truth and good; "He made him to suck honey out of the cliff" signifies that they had natural good by means of truths; "oil out of the flint of the rock" signifies that they had spiritual good also by means of truths; "honey" and "oil" signifying those goods, and "cliff," "rock," and "hard rock," signifying truths; "butter of the herd, and milk of the flock," signify the internal and the external good of truth; "the fat of lambs, of the rams of Bashan, and of goats," signifies the goods of innocence of the three degrees (as above); "the fat of the kidneys of wheat" and "the blood of the grape" signify genuine good and genuine truth therefrom.

[8] In Isaiah:

The sword of Jehovah shall be filled with blood; it shall be made fat with fatness, with the blood of lambs and of he-goats, and with the fat of the kidneys of rams (Isaiah 34:6).

Here, too, "lambs, rams, and goats," signify the three degrees of the good of innocence (of which above); but here their destruction by the falsities of evil is treated of; for "sword" signifies falsity destroying truth and good; the "blood" with which it shall be filled signifies destruction.

[9] Since a "lamb" signifies innocence, which, viewed in itself, is love to the Lord, a "lamb," in the highest sense, signifies the Lord in respect to the Divine Human, for in respect to this, the Lord was innocence itself; as may be seen in the following passages. In Isaiah:

He endured persecution and He was afflicted, yet He opened not His mouth; He is led as a lamb to the slaughter (Isaiah 53:7).

Send ye the lamb of the ruler of the land from the cliff toward the wilderness unto the Mount of the daughter of Zion (Isaiah 16:1).

In John:

John seeth Jesus coming unto him, and saith, Behold the Lamb of God, that taketh away the sin of the world. And afterwards, seeing Jesus walking, he said, Behold the Lamb of God (John 1:29, 36).

And in Revelation:

The Lamb in the midst of the throne shall feed them, and shall lead them unto living fountains of waters (Revelation 7:17).

They overcame by the blood of the Lamb, and by the Word of the testimony (Revelation 12:11;

besides also elsewhere in Revelation (as Revelation 13:8; 14:1, 4; 17:14; 19:7, 9; 21:22-23; 22:1, 3).

[10] Since "burnt-offerings and sacrifices" signified all representative worship from the good of love and from the truths thence, "burnt-offerings" worship from the good of love, and "sacrifices" in a special sense worship from the truths thence, so:

Every day, evening and morning, there was a burnt-offering of lambs (Exodus 29:38-43; Numbers 28:1-9);

Every sabbath, of two lambs, besides the continual burnt-offering of them (Numbers 28:9-10);

In the beginnings of the months, of seven lambs (Numbers 28:11-15);

Likewise on the day of the firstfruits (Numbers 28:26 to end);

Likewise in the seventh month, when there was a holy convocation (Numbers 29:1-7);

Likewise, namely of seven lambs on each day of the passover, besides two young bullocks, one ram, and one goat (Numbers 28:16-24).

The burnt-offering was of "seven lambs" because "seven" signifies all and fullness, and it is predicated of what is holy, and because "burnt-offerings" in general signified worship of the Lord from the good of love, and the good of love to the Lord from the Lord is the good itself of innocence; and "lamb" in the highest sense signified the Lord in respect to the Divine Human. (That "burnt-offerings" signified all worship from the good of love to the Lord from the Lord, see Arcana Coelestia 923, 6905, 8680, 8936, 10042) On account of this representation there was also instituted:

The supper of the passover of lambs or kids (Exodus 12:1-29);

for "the feast of the passover" represented the glorification of the Lord's Human (See Arcana Coelestia 10655). Because "infants" signified innocence, it was also commanded that:

After birth, on the day of purification, they should sacrifice a lamb, a young pigeon, or a turtle dove; or, instead of a lamb, two young pigeons or two turtle doves (Leviticus 12:6, 8);

"young pigeons" and "turtle doves" signifying the like as "lambs," namely, innocence.
