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.

7906. 'No yeast shall be found in your houses' means no falsity whatever shall come near good. This is clear from the meaning of 'yeast' as falsity, dealt with below; and from the meaning of 'house' as good, dealt with in 3652, 3720, 4982, 7833-7835. The meaning of 'yeast' as falsity becomes clear from the places where yeast and anything made with yeast, and also where unleavened and anything made without yeast are mentioned, such as in Matthew,

Jesus said, Look out for and beware of the yeast of the Pharisees and Sadducees. Then the disciples understood that He had not said that they should beware of the yeast used in bread, but of the teaching of the Pharisees and Sadducees. Matthew 16:6, 11.

Here 'yeast' plainly stands for false teaching. Because 'yeast' meant falsity it was forbidden to sacrifice the blood of the sacrifice with anything made with yeast, Exodus 23:18; 34:25. For 'the blood of the sacrifice' meant holy truth, thus truth pure and free from all falsity, 4735, 6978, 7317, 7326, 7846, 7850. It was also laid down that the minchah offered on the altar should not be baked with yeast in it, Leviticus 6:15-17, and that cakes and wafers also should be made without yeast, Leviticus 7:11-13.

[2] To go further with what 'made with yeast' and 'not made with yeast' refer to, it should be recognized that the purification of truth from falsity cannot ever come about in a person without so called fermentation, that is, without the conflict of falsity with truth and of truth with falsity. But after the conflict has taken place and truth has triumphed, the falsity falls away like dregs and the truth emerges purified. It is like wine that becomes clear after fermentation as the dregs sink to the bottom. That fermentation or conflict takes place especially when a person's state undergoes a change, that is to say, when his actions begin to spring from the good of charity, and not as previously from the truth of faith. For a person's state is not yet made pure while his actions spring from the truth of faith, but they have been made pure when they spring from the good of charity, since they now spring from his will. Previously they sprang merely from his understanding.

[3] Spiritual conflicts or temptations are fermentations in the spiritual sense, for during them falsities wish to link themselves to truths, but the truths reject them, eventually sending them to the bottom so to speak and in that way becoming refined. This is the sense in which to understand what the Lord teaches about 'yeast' in Matthew,

The kingdom of heaven is like yeast, which a woman took and hid in three measures of flour, until the whole was fermented by it. Matthew 13:33.

'Flour' is truth from which good is derived. Also in Hosea,

They are all committing adultery, like an oven heated by a baker; the raiser ¹ ceases from kneading the dough until it has fermented. Hosea 7:4.

Since such conflicts, meant by 'fermentations', take place with a person in the state before he attains newness of life, as has been stated, it was also laid down that the new minchah, the bread of the wave-offering, that was to be brought at the feast of first fruits, should be baked with yeast; and that was to be the first fruits to Jehovah, Leviticus 23:16-17.
