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).
