Didn’t land ownership also revert back to the original owners, or thier heirs, during Jubilee?
Yes. I think the Year of Jubilee was actually every 49 years. Every seven years was a Sabbatical year and all personal debts were to be forgiven and every seventh Sabbatical year was a year of Jubilee and all debts were forgiven, slaves were freed and land returned to the original owners. Houses inside walled cities were excepted from the Year of Jubilee, as they were simply homes and not farmland designed to make a profit. I think the intent of the land clause was to keep one individual or family from moving to a point where they owned everything and everyone else was a tenant. I remember reading it and thinking how much sense that would make in terms of preventing the kinds of problems we have now. Of course, part of it was specific to Israel, particularly the part about land, as it was implemented right after they moved into Canaan, and every family started out with an equal amount of land.
It recognized that some people were better at life than others, and that some would fall inexorably into debt while others accumulated everything.
