Just as natural food feeds the natural body, so too does spiritual food feed the spiritual body. And since our spiritual body is the expression of what we love, then spiritual food is what feeds our state of love: It is the desire for good, the delight of being good, the understanding of what it is to be good and the knowledge of all that's true and leads to what is good. So when food is talked about in the Bible, that's what it means, and the huge variety of forms food can take represent the huge variety of good we can seek in life and the huge variety of thought we can have leading to it.

9003. 'He shall not diminish her food, her clothing, and [her] marital rights' means no deprivation of inner life meant by 'food', nor of outer life meant by 'clothing', thus no deprivation of the joining together meant by 'marital rights'. This is clear from the meaning of 'food' as the sustaining of inner life, for in the spiritual sense 'food', both solid and liquid, is cognitions or the knowledge of good and truth, solid food being cognitions of good, 5147, and 'drink' cognitions of truth, 3168, 3772, so that 'food' is the things that nourish a person's spiritual life, 5293, 5576, 5579, 5915, 8562; from the meaning of 'clothing' as the sustaining of outer life, for in the spiritual sense 'clothing' or garments are inferior factual knowledge, this knowledge being that which spiritually sustains a person's outer life, 5248, 6918; from the meaning of 'marital rights' as a joining together; and from the meaning of 'not diminishing' as not depriving.

[2] The situation here is that a natural affection joined to a spiritual truth, which is meant by 'a female slave betrothed to a son', unceasingly needs to be sustained with life from the spiritual truth to which it has been joined; if the affection is not sustained from there it perishes. The situation with a person's affection is just the same as with the person himself; if he is not sustained by food he dies. Interiorly furthermore a person is nothing other than affection, one who is good being interiorly an affection for good and consequently for truth, and one who is evil being an affection for evil and consequently for falsity. This is especially evident in a person when he becomes a spirit; the sphere of life which then wells out of him is either one of affection for good or one of affection for evil. Now he is nourished or sustained not with natural food and drink but with spiritual, which for an evil spirit is falsity arising from evil, but for a good spirit is truth springing from good. The nourishment that people's minds receive in the world during their life in the body is nothing other. So it is that all kinds of food - bread, flesh, wine, water and many others - mean in the spiritual sense within the Word the kinds of food that constitute spiritual nourishment.

[3] All this also shows what one is to understand by the Lord's words in Matthew,

Man does not live by bread only but by every word that goes out of the mouth of God. Matthew 4:4.

Also what one should understand by His words in Luke,

You will eat and drink at My table in My kingdom. Luke 22:30.

And in Matthew,

I tell you that I shall not drink from now on of this fruit of the vine until that day when I drink it new with you in My Father's kingdom. Matthew 26:29.

The Lord spoke these words after He had instituted the Holy Supper, in which the bread and wine are elements which denote love and faith, in the same way as flesh and blood do. From this it can be clearly seen what the Lord's flesh and blood mean in John 6:49-58, especially in these words there,

My flesh is truly food, and My blood is truly drink. John 6:55.

In the Word 'flesh' means the good of love, see 3813, 7850, 'blood' the good of faith, 4735, 6978, 7317, 7326, 7846, 7850, 7877; and 'bread' and 'wine' have the same meanings, 2165, 2177, 3464, 3478, 3735, 3813, 4211, 4217, 4735, 4976, 5915, 6118, 6377.
