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.

6109. 'And there was no bread in all the land' means that good was not apparent any longer. This is clear from the meaning of 'bread' as the good of love and charity, dealt with just above in 6106; and from the meaning of 'none in all the land' as the fact that none was apparent any longer. The subject in what follows below is the internal celestial, how it brought everything in the natural into order beneath the general whole, to the end that factual knowledge might become joined to the Church's truths, and through those truths to spiritual good, and through this good to the internal celestial. But since factual knowledge cannot be brought into order beneath the general whole except through stages when good is laid waste and truth is made desolate, and then by stages of sustainment, both the latter and the former stages are dealt with in the internal sense of what follows next. These things rarely happen to a person while he lives in the world, for a number of reasons; but in the next life they happen to all who are being regenerated. And since they do not happen to a person while he is in the world it is not surprising if they appear to him as things unknown and strike him as deep secrets about which no one has heard before.
