In Ezekiel 47:21, this signifies all the elements belonging to faith. (Arcana Coelestia 1463[2])

'A tribe' signifies the church with respect to its truths and goods, and in the opposite sense, with respect to its falsities and evils. It also signifies the church with respect to religion.

Three first tribes of Israel, Judah, Reuben, and Gad, signify love to the Lord. Asher, Naphtali, and Manasseh signify charity towards our neighbor. Simeon, Levi, and Issachar signify the obedience of faith. The last three tribes, Zebulon, Joseph, and Benjamin, named in this order, signify the conjunction of all the above with the Lord. Their significances are according to the order in which they are named in Revelation 7. In general, 'the twelve tribes' signify every aspect of the doctrine of truth and good, or of faith and love. Truth and good, or faith and love, constitute the Lord's kingdom, because the elements of truth or faith are the whole of thought in it, and the elements of good or love are the whole of affection. As the Jewish church was instituted to represent the Lord's kingdom, the divisions of the people into twelve tribes had this significance. This is an arcanum which has not been discovered before now (the volumes of Arcana Coelestia were published from 1749 to 1756).

575. And the dragon gave it its power, its throne, and great authority. This symbolically means that this heresy prevails and reigns as a result of its acceptance by the laity.

The dragon symbolizes this heresy, as explained in no. 537. The beast here symbolizes the laity (no. 567), who do not speak on their own, but quote their teachers, and because the laity constitute the populace, it is apparent that this heresy prevails and reigns owing to their acceptance of it.

This, then, is what is symbolized by the power, throne and great authority that the dragon gave this beast, and by the following statement in verse 4, "Then they worshiped the dragon which gave authority to the beast."

The dragon prevails and reigns through these people, especially through this dogma of their religion, that the intellect must be held captive in obedience to faith; that faith is something that is not understood; and that in spiritual matters, a faith in something that is understood is an intellect-oriented faith, which is not justifying.

When this faith prevails among the laity, the clergy have power, veneration, and a kind of worship on account of the Divine things which they are believed by the laity to know, and which the laity soak up on their authority.

Power symbolizes influence, a throne government, and great authority dominion.
