'Reuben,' in the highest sense, signifies omniscience. In a spiritual sense, he signifies wisdom, intelligence, science, and faith. In a natural sense, he signifies sight. In Revelation 7:5, 'Reuben' signifies wisdom because he comes after Judah, who signifies celestial love, and celestial love produces wisdom because no love exists without its consort, which is science, intelligence, and wisdom. The consort of natural love is science, the consort of spiritual love is intelligence, and the consort of celestial love is wisdom. 'Reuben' signifies these things because he was named for 'seeing' or 'sight,' and spiritual-natural sight is science, spiritual sight is intelligence, and celestial sight is wisdom. Also, 'Reuben' was the firstborn of Jacob, and was therefore called his 'might, the beginning of [his] strength, excelling in eminence, and excelling in worth.' This is the nature of wisdom originating in celestial love. Because 'Reuben' was the firstborn, he represents and signifies the wisdom of the people of the church. This is why he urged his brothers not to kill Joseph, and grieved when Joseph was not found in the pit in Genesis 37:21, 22. This is also why his tribe camped in the south, and was called 'the camp of Reuben.' The south also signifies wisdom originating in love, which is people in this wisdom in heaven dwell to the south. 'The tribe of Reuben' in an opposite sense symbolizes wisdom divorced from love, and faith divorced from charity. This is why his father Israel cursed him in Genesis 49:3, 4. He was also deprived of his birthright in 1 Chronicles 5:1. For the same reason the tribe was given an inheritance across the Jordan and not in the land of Canaan. Ephraim and Manasseh, Joseph's sons, were also acknowledged in place of Reuben and Simeon in Genesis 48:5. Nevertheless, he still retains the positive representation and symbolism of wisdom.

6225. 'And Israel strengthened himself' means new powers received through spiritual good. This is clear from the meaning of 'strengthening oneself' as receiving new powers; and from the representation of 'Israel' as spiritual good from the natural, dealt with in 4286, 4598, 5801, 5803, 5806, 5812, 5817, 5819, 5826, 5833. The reason the new powers come through spiritual good is that in what has just been said Jacob is called Jacob but now he is called Israel; for this is what is said,

[Someone] told Jacob and said, Behold, your son Joseph has come to you; and Israel strengthened himself.

For 'Israel' is spiritual good from the natural, whereas 'Jacob' is the truth of the natural, and the truth of the natural, which is the truth of faith there, receives its strength through spiritual good, which is the good of charity. Also, 'Israel' is the internal aspect of the Church and 'Jacob' its external aspect, 4286, 4292, 4570. The external aspect of the Church derives its strength and receives its powers from nowhere else than its internal. The internal aspect of the Church exists among those governed by the good of charity, which is the good of faith, also the good of truth, and spiritual good as well, which are 'Israel'. But the external aspect of the Church exists among those governed by the truth of faith. They are not yet plainly governed by good; yet the truth they are governed by holds good within it, and this is 'Jacob'.
