8562. And there was no water for the people to drink. That this signifies a lack of truth and of the consequent refreshment, is evident from the signification of “water,” as being the truth of faith (see n. 2702, 3058, 3424, 4976, 5668); and from the signification of “drinking,” as being to be instructed in the truths of faith and to receive them (n. 3069, 3772, 4017, 4018), here, to be refreshed; for as water and drink refresh the natural life, so truths and the knowledges of truth refresh the spiritual life. For he who is in spiritual life longs for the sustenance thereof from such things as are called heavenly food and drink, which are the goods and truths of faith; in like manner as he who is in natural life longs for sustenance from such things as are natural food and drink.

[2] That temptation as to truth is now treated of, is because temptation as to good was treated of just before, after which temptation they received the manna, by which is signified good. For when man is endowed with good by the Lord, he comes into a longing for truth, and this longing is kindled according to the lack of truth, because good continually strives after truth. All the genuine affection of truth is from good. The case herein is like food, which without drink cannot nourish the natural life; and it is also like it in that food longs for drink, with which it may be conjoined so as to serve for use. This then is the reason why temptation as to truth follows immediately after temptation as to good. Temptation attacks that which a man loves and longs for (n. 4274, 4299).

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.
