8770. 'And you will be for Me a kingdom of priests' means that at that time the good of truth will be [with them]. This is clear from the meaning of 'a kingdom of priests' here as spiritual good, which is the good of truth, that is, the good that a member of the spiritual Church is brought to by means of truth. The reason why 'a kingdom of priests' means this good is that these words are addressed to the house of Jacob and the children of Israel, who represent the spiritual Church, external and internal - the house of Jacob representing the external Church, and the children of Israel the internal Church, 8762. Also 'a kingdom' means truth, 1672, 2547, 4691, while 'priests' means good, since the Lord's Priesthood, which was represented by priests, means Divine Good, and the Lord's Kingship, which was represented by kings, means Divine Truth, 1728, 2015 (end), 3670, 6148.

[2] In the representative Church among the descendants of Jacob there was first a kingdom ruled by judges, after that a kingdom ruled by priests, and finally a kingdom ruled by kings. The kingdom ruled by judges represented Divine Truth emanating from Divine Good, whereas the kingdom ruled by priests, who were also judges, represented Divine Good from which Divine Truth emanates, and the kingdom ruled by kings represented Divine Truth without Divine Good. But when the office of king also had some of the priestly functions attached to it, kings then also represented Divine Truth containing good in the measure that priestly functions were linked to the office of king.

[3] All this was brought about in the Jewish Church to the end that the states of heaven might thereby be represented. For in heaven there are two kingdoms, one being called the celestial kingdom, and the other being called the spiritual kingdom. The celestial kingdom is what is called the Lord's Priesthood, and the spiritual kingdom is what is called His Kingship. In the latter Divine Truth reigns, in the former Divine Good. And since the representation of the celestial kingdom began to perish when the people asked for a king, therefore - to ensure that something representing the Lord's kingdom in the heavens might nevertheless continue to exist - the Jews were separated from the Israelites. The Jewish kingdom then represented the Lord's celestial kingdom, and the Israelite kingdom His spiritual kingdom.

[4] If people know these things they are able to know why the changes in forms of government took place one after another among the descendants of Jacob. They are also able to know why, when the people asked for a king, they were told by Jehovah through Samuel that in doing so they rejected Jehovah so that He should not reign over them, 1 Samuel 8:7, and why they were told then about 'the right of the king', 1 Samuel 8:11 and following verses, which describes Divine Truth without Divine Good. If people know the things mentioned above they can also know why some priestly functions were conferred on David, and also why after Solomon's time the kingdom was divided into two, into the Jewish kingdom and the Israelite kingdom. Regarding the two kingdoms in heaven, see 3635, 3883-3896, 4112, 4113, 4138.

4691. 'Are you indeed going to reign over us? Or are you indeed going to have dominion over us?' means, Were the concepts in their understandings and the desires in their wills to be made subject to it? This is clear from the meaning of 'reigning' as the subjection of concepts in the understanding, and from the meaning of 'having dominion' as the subjection of desires in the will. This meaning of 'reigning over them' and 'having dominion over them' - being made subject to - is self-evident; but the reason both expressions are used here is that one has regard to concepts in the understanding, the other to desires in the will. It is common in the Word, especially in the prophetical part, for one particular matter to be described by a dual expression. Anyone unaware of the arcanum lying behind this inevitably supposes that it is no more than a repetition made for the sake of emphasis. But that is not the case. Within every single part of the Word the heavenly marriage is present, namely the marriage of truth to good and of good to truth, just as there is a marriage of understanding and will in the human being. One part of a dual expression has reference to truth, the other to good, so that one has to do with the understanding since that is where truth belongs, the other with the will since this is where good belongs. Expressions used in the Word consist of words which in every case mean things like these. This is the arcanum lying behind the use of a dual expression to describe one particular matter, see 683, 793, 801, 2173, 2516, 2712, 4138(end). So that is the case here also with 'reigning over them' and 'having dominion over them'. 'Reigning' has regard to truth which belongs in the understanding, while 'dominion' has regard to good which belongs in the will; also, 'a kingdom' is used in reference to truth, 1672, 2547, and 'dominion' to good, as is also the case in Daniel where again the Lord's Divine Human is the subject,

To Him was given dominion and glory and kingdom, so that all peoples, nations and languages might worship Him. His dominion is an eternal dominion which will not pass away, and His kingdom one that will not perish. Daniel 7:14.

And in David,

Your kingdom is a kingdom to all eternity, and Your dominion to every generation after generation. Psalms 145:13.
