9373. Come up unto Jehovah. That this signifies conjunction with the Lord, is evident from the signification of “coming up,” as being to be raised toward interior things (see n. 3084, 4539, 4969, 5406, 5817, 6007), consequently also to be conjoined (n. 8760). That it denotes conjunction with the Lord, is because by “Jehovah” in the Word is meant the the Lord, (n. 1343, 1736, 1793, 2004, 2005, 2018, 2025, 2921, 3023, 3035, 5663, 6280, 6303, 6905, 8274, 8864, 9315). A secret which also lies hidden in the internal sense of these words, is that the sons of Jacob, over whom Moses was the head, were not called and chosen; but they themselves insisted that Divine worship should be instituted among them (according to wh at has been said in n. 4290, 4293); and therefore it is here said, “and He said unto Moses, Come up unto Jehovah,” as if not Jehovah, but another, had said that he should come up. For the same reason in what follows it is said that “the people should not go up” (verse 2); and that “Jehovah sent not His hand unto the sons of Israel who were set apart” (verse 11); and that “the appearance of the glory of Jehovah was like devouring fire on the top of the mountain in the eyes of the sons of Israel” (verse 17); and lastly that Moses, being called the seventh day, “entered into the midst of the cloud.” For by “the cloud” is meant the Word in the letter (n. 5922, 6343, 6752, 6832, 8106, 8443, 8781); and with the sons of Jacob the Word was separated from its internal sense, because they were in external worship without internal, as can be clearly seen from the fact that now, as before, they said, “all the words which Jehovah hath spoken we will do” (verse 3); and yet scarcely forty days afterward they worshiped a golden calf instead of Jehovah; which shows that this was hidden in their hearts while they were saying with their lips that they would serve Jehovah alone. But nevertheless those who are meant by “the called and the chosen” are those who are in internal worship, and who from internal worship are in external; that is, those who are in love to and faith in the Lord, and from this in love toward the neighbor.

4792. As food and nourishment correspond to spiritual food and nourishment, therefore taste corresponds to the perception and affection of this food. Spiritual food is knowledge, intelligence, and wisdom, for from these, spirits and angels live and are nourished, and they desire and have appetite for them just as men who are hungry desire and have appetite for food. Hence appetite corresponds to this desire. And wonderful to say, from this food they grow to maturity; for little children who die appear in the other life no otherwise than as little children, and also are such as to understanding; but as they increase in intelligence and wisdom, they appear not as little children, but as advancing in age, and at last as adults. I have conversed with some who had died in infancy, and were seen by me as young men, because they were then intelligent. From this it is evident what spiritual food and nourishment are.

5293. 'And let them gather all the food' means all things that have a useful purpose. This is clear from the meaning of 'gathering' as drawing together and preserving; and from the meaning of 'food' as things which have a useful purpose. In the internal sense 'food' means, strictly speaking, those things which nourish a person's soul, that is, which nourish him when his bodily life is ended. For when this is ended his soul or spirit is living, and he no longer needs material food as he did in the world; but he does need spiritual food, which consists in everything that has a useful purpose and everything leading to this. That which leads to what has a useful purpose is knowing what goodness and truth are; and that which has such a purpose is the desire to realize these in actions. These are the things with which angels are nourished and which are therefore called spiritual and celestial foods. A person's mind - the place within him where his will and understanding, that is, his intentions or ends in view, reside - is nourished by no other kind of food, even while he lives in the body. Material food does not extend as far as that; it extends only to his bodily parts, which are sustained by that material food to the end that the mind may be sustained by food for the mind while the body is sustained by food for the body, that is, to the end that there may be a healthy mind in a healthy body.

[2] The reason 'food' in the spiritual sense means everything that has a useful purpose is that a person's entire knowledge, his entire understanding and wisdom, and so his entire will must have a useful purpose as its end in view. Consequently as is the nature of the purpose he has in view, so is the nature of his life. The truth that 'food' in the spiritual sense means everything with a useful purpose is evident from the following words spoken by the Lord,

Jesus said to the disciples, I have food to eat of which you do not know. The disciples said to one another, Has anyone brought Him anything to eat? Jesus said to them, My food is to do the will of Him who sent Me, and to accomplish His work. John 4:32-34.

And elsewhere,

Do not labour for the food which perishes, but for the food which endures to eternal life, which the Son of Man will give you. On Him the Father - God - has set His seal. John 6:27.
