9925. 'When he ministers' means while engaged in worship and preaching the gospel. This is clear from the meaning of 'ministering' - when said of Aaron, who represents the Lord - as worship and preaching the gospel. By this worship is meant everything representative of that worship which springs from the good of love and the truths of faith. For worship that springs from these is indeed worship; but worship devoid of them is like the shell without the nut, and like the body without the soul. This is what the worship among the Jewish and Israelite nation was like, since their worship did no more than represent inward things, which are those of love and faith, as has been stated. Even so, the Lord saw to it that such worship should be discerned in the heavens, so that through it a link with mankind might be established, not through inner things but through the correspondences of these with outward things, regarding which, see the places referred to in 9320 (end), 9380. This worship is what is meant by Aaron's ministering.

[2] The reason why preaching the gospel is also meant is that preaching the gospel implies all those things in the Word which have to do with the Lord, and all those in worship which served to represent Him. For preaching the gospel involves declaring the truth about the Lord, about His Coming, and about the things of which He is the author, namely things that belong to salvation and eternal life. And since everything in the Word in its inmost sense has to do solely with the Lord, and also everything in worship served to represent Him, the whole of the Word is the gospel, as likewise was all the worship which was performed in accord with what was commanded in the Word. And since the priests had charge of worship, and also gave instruction, worship and preaching the gospel were meant by their ministry.

4976. 'And ministered to him' means that factual knowledge was assigned to its own good. This is clear from the meaning of 'ministering' as serving by supplying what another has need of, in this case as being assigned to since the subject is natural good to which factual knowledge is to be assigned. 'Ministering' is also used to describe known facts, for in the Word a minister and a servant mean factual knowledge or natural truth because this is subservient to good as its lord. Factual knowledge stands in relation to delight present in the natural man - or what amounts to the same, natural truth stands in relation to its good - in exactly the same way as water does to bread, or drink to food. Water or drink enables bread or food to be dissolved, and once dissolved to be conveyed into the blood, from which it passes into all parts around the body and nourishes them. Without the water or drink the bread or food is not broken down into extremely small particles and carried around the body to fulfill its purpose.

[2] The same applies to factual knowledge in relation to delight, or truth in relation to good. That being so, good longs for and desires truth, and does so because of the purpose such truth can fulfill by ministering to it and serving it. Food and drink also correspond to these. No one in the next life is nourished by any natural food or natural drink, only by spiritual food and spiritual drink, spiritual food being good, and spiritual drink truth. This is why, when bread or food is mentioned in the Word, angels understand spiritual bread or food, which is the good of love and charity; and when water or drink is mentioned they understand spiritual water or drink, which is the truth of faith. From this one may see what the truth of faith without the good of charity is, and also what kind of nourishment the former without the latter is able to supply to the internal man; that is to say, it is like the nourishment supplied by water or drink alone without bread or food. It is well known that a person fed on water or drink alone wastes away and dies.
