5915. And I will sustain thee there. That this signifies continuous influx of spiritual life from the internal celestial, is evident from the signification of “sustaining,” when it is said by Joseph, by whom is represented the internal celestial, as being the influx of spiritual life from the internal celestial; sustenance in the spiritual sense being nothing else than the influx of good and of truth through heaven from the Lord. From this are the angels sustained, and from this is the soul of man (that is, his internal man) sustained. To this sustenance corresponds the sustenance of the external man by food and drink; and therefore by “food” is signified good, and by “drink,” truth. Such also is the correspondence, that when a man is partaking of food, the angels with him are in the idea of good and truth, and wonderful to say with a difference according to the species of the food. Thus when a man in the Holy Supper receives the bread and the wine, the angels with him are in the idea of the good of love and the good of faith (n. 3464, 3735), for the reason that bread corresponds to the good of love, and wine to the good of faith; and because they correspond, they also signify the same in the Word.

[2] That man’s soul (that is, the internal man) is sustained by spiritual food and drink, that is, by good and truth, is evident from the Lord’s words in Moses:

Man doth not live by bread only, but by every utterance of the mouth of Jehovah doth man live (Deuteronomy 8:3; Matthew 4:4).

The “utterance of the mouth of Jehovah” is the good and the truth which proceed from Him.

In John:

Labor not for the food which perisheth, but for the food which remaineth into eternal life, which the Son of man will give you (John 6:27).

Again:

The disciples besought Jesus, saying, Master, eat. He said to them, I have food to eat that ye know not (John 4:31-32).

And concerning drink, in the same:

Jesus said, If anyone thirst, let him come unto me and drink; whosoever believeth in Me, as the Scripture hath said, out of his belly shall flow streams of living water (John 7:37-38).

5293. And let them gather all the food. That this signifies all things that are of use, is evident from the signification of “gathering,” as being to bring together and preserve; and from the signification of “food,” as being things that are of use. In the internal sense “food” properly signifies the things that nourish the soul of man, that is, that nourish him after death, for he then lives as a soul or spirit, and no longer needs material food, but spiritual food, which consists in everything that is of use, and everything that is conducive to use. That which is conducive to use is to know what is good and true; that which is of use is to will and do what is good and true. These are the things that nourish the angels, and are therefore called spiritual and heavenly food. Man’s mind within which are his interior understanding and interior will, or his intentions or ends, is not nourished by any other food even while he lives in the body. Material food does not penetrate to the mind, but only to the things of the body, which that food sustains to the end that this mind may enjoy its food while the body enjoys its food, that is, that this mind may be sound in a sound body.

[2] That “food” in the spiritual sense denotes everything that is of use, is because all man’s knowing, and all his understanding and being wise, and therefore all his willing, ought to have use for their end; hence the quality of his life is according to the quality of his use. That “food” in the internal sense denotes everything that is of use, is plain from these words of the Lord:

Jesus said to the disciples, I have food to eat that ye know not of. Therefore said the disciples one to another, Hath any man brought Him aught to eat? Jesus saith unto them, My food is to do the will of Him that sent Me, and to perfect His work (John 4:32-34); and in another place:

Labor not for the food that perisheth, but for that food that remaineth unto eternal life, which the Son of man shall give unto you; for Him hath God the Father sealed (John 6:27).
