It is fitting that to “sojourn” in the Bible -- to live in a foreign land -- represents instruction, learning the things represented by that area. This is used quite a bit in the early parts of the Bible, when Abraham and his immediate descendants sojourned in a variety of foreign places. It arises also later in the Old Testament, with the Israelites given rules on how to treat sojourners in their midst.

The sojourner is a person who is willing to learn and accept new spiritual truths. That's in contrast to the term "stranger", as used in the Bible. A stranger has a natural inclination to good, but is not willing to learn spiritual truths. There is a long history of using travel to round out an education, from the 19th-century “world tours” taken by Oxford and Cambridge graduates to the exchange programs and semesters abroad offered in modern school programs. The idea is pretty straightforward: by immersing ourselves in other cultures we can both learn about them and deepen our minds.

6102. 'And Joseph caused his father and his brothers to dwell' means the life which spiritual good and the Church's truths received from the internal celestial. This is clear from the meaning of 'dwelling' as life, dealt with in 1293, 3384, 3613, 4451, 6051; from the representation of Israel, to whom 'father' refers here, as spiritual good from the natural, dealt with in 5801, 5803, 5806, 5812, 5817, 5819, 5826, 5833; from the representation of his sons, to whom 'brothers' refers here, as the Church's truths in the natural, dealt with in 5414, 5879, 5951; and from the representation of 'Joseph' as the internal celestial, dealt with in 5869, 5877. From all this it is evident that 'Joseph caused his father and his brothers to dwell' means the life which spiritual good and the Church's truths received from the internal celestial.
