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.

418. The previous verse deals with celestial things, which are the attributes of love, the present verse with spiritual things, which are the attributes of faith. These spiritual things are portrayed as 'the harp and organ'. That stringed instruments, such as harps and others like them, meant the spiritual things of faith is clear from many points of view. In the worship of the representative Church instruments like these, and the singing likewise, had no other representation. This was why there were so many singers and musicians, the main reason for such representation being that all heavenly joy produces gladness of heart, which was expressed by means of singing, and subsequently by means of stringed instruments that strove to match the singing and uplifted it. Every affection of the heart also has this capacity to produce singing and therefore the things which go with singing. Affection of the heart is something celestial, singing issuing from it something spiritual.

[2] That singing and the like means that which is spiritual has also become clear to me from angelic choirs, of which there are two kinds, celestial and spiritual. From the vibrant quality of their singing, to which the sound of stringed instruments may be likened, spiritual choirs are readily distinguished from celestial choirs. This will in the Lord's Divine mercy be described later on. What is more, the most ancient people related that which was celestial to the province of the heart, and that which was spiritual to the province of the lungs. In so doing they related that which was spiritual to whatever involved the lungs, such as singing voices and other similar things, and so to the voices or sounds of such instruments. The reason for their so relating them was not only that the heart and lungs represent a kind of marriage, like that of love and faith, but also that celestial angels belong to the province of the heart whereas spiritual angels belong to that of the lungs. It can also be recognized that such considerations are meant here from the fact that this is the Word of the Lord, which would contain no life at all if its message were merely that Jubal was the father of those who play on harp and organ. Nor would any use be served in anyone's knowing it.
