3861. 'And she called his name Reuben' means the essential nature of it, which is described. This is clear from the meaning of 'name' and 'calling the name' as the essential nature, dealt with in 144, 145, 1754, 1896, 2009, 2724, 3006, 3421. That nature itself is described by the statement, 'Because Jehovah has seen my affliction, for now my husband will love me', the literal meaning of the name Reuben. Spiritually however all names in the Word mean real things, as has been shown often, see 1224, 1264, 1876, 1888; and among me ancients when a name was given it meant some state, 340, 1946, 2643, 3422. Here it will be seen that the names of all the sons of Jacob mean the universal attributes of the Church. Also one specific universal attribute has been combined within each name, but what that attribute is no one can possibly know unless he knows the internal sense embodied in the words from which each son's name is derived. That is, he needs to know the internal sense embodied in 'has seen' from which Reuben is derived, and in 'has heard' from which Simeon is derived, and in 'has clung to' from which Levi is derived, and in 'to confess' from which Judah is derived, and so on with all the other sons.

114. The truth of faith was also meant and represented in the Word precious stones, for example, those in the breast plate of judgement, and upon the shoulder-pieces of Aaron's ephod. in the breastplate, the gold, blue, purple, double-dyed scarlet, and fine-twined linen represented matters of love, while the precious stones represented matters of faith deriving from love, as did the two stones of remembrance on the shoulder-pieces of the ephod which were made from shoham encompassed with settings of gold, Exodus 28:9-22. The same point, that the truth of faith is meant and represented by precious stones, is plainly stated in Ezekiel when the subject is the person who possesses the heavenly riches of wisdom and intelligence,
Full of wisdom and perfect in beauty, you were in Eden, the garden of God. Every precious stone was your covering ruby, topaz, diamond, tarshish, shoham, and jasper, sapphire, chrysoprase, and emerald. And gold, the work of your drums and of your pipes, was within you. On the day that you were created they were prepared. You were perfect in your ways from the day you were created. Ezekiel 28:12-13, 15.
Anyone may see that celestial and spiritual things of faith, and not just stones, are meant. Indeed each stone represented a particular essential element of faith.
