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.

489. "And they will tread the holy city underfoot for forty-two months." This symbolically means that the church has dispelled every truth of the Word to the point that none remains.

The holy city means the Holy Jerusalem, and the Holy Jerusalem means the New Church which possesses doctrinal truths, as holiness is predicated of Divine truth (no. 173). A city, moreover, symbolizes doctrine (no. 194). Consequently to tread that city underfoot means, symbolically, to dispel its doctrinal truths. Forty-two months mean, symbolically, to the end when nothing remains.

Doctrinal truths mean truths from the Word, because that is the source of the church's doctrine and every particular of it.

People concerned with the internal elements of the church today have thus dispelled the Word's truths and the church's doctrine from it. All of this is described in the present chapter by the beast ascending from the bottomless pit, which killed the two witnesses (verse 7); and it may also be seen from the accounts from the spiritual world appended to each chapter.

[2] Forty-two months mean, symbolically, to the end when nothing of the church's truth and goodness remains, because the number forty-two has the same symbolic meaning as six weeks, inasmuch as forty-two is the product of six multiplied by seven, and six weeks symbolizes a period complete to the end. For that is the symbolic meaning of the number six, and a week symbolizes a state, and the seventh week a holy state, which is the new state of the church when the Lord begins His reign.

The number forty-two has the same symbolic meaning in the following verse:

(The beast rising up out of the sea) was given a mouth speaking great things and blasphemies, and it was given the power to do this for forty-two months. (Revelation 13:5, no. 583)

The number six symbolizes a period complete to the end because that is the symbolic meaning of the number three, six being that number doubled; and doubled or not, in the case of numbers the symbolism is the same.

Furthermore, this number has the same symbolic meaning as the number three and a half, because forty-two months is equivalent to three and a half years.

The period is expressed in terms of months because a month symbolizes a complete state, as in Isaiah 66:23, Revelation 22:1-2, Genesis 29:14, Numbers 11:18-20, Deuteronomy 21:11, 13.
