Thus the symbol is expounded: Israel's tenure of the Promised Land will survive the Captivity; the Jews will return to resume their inheritance, and will again deal with the old fields and vineyards and oliveyards, according to the solemn forms of ancient custom.
The familiar classical parallel to this incident is found in Livy, xxvi. 11, where we are told that when Hannibal was encamped three miles from Rome, the ground he occupied was sold in the Forum by public auction, and fetched a good price.
Both at Rome and at Jerusalem the sale of land was a symbol that the control of the land would remain with or return to its original inhabitants. The symbol recognised that access to land is essential to all industry, and that whoever controls this access can determine the conditions of national life. This obvious and often forgotten truth was constantly present to the minds of the inspired writers: to them the Holy Land was almost as sacred as the Chosen People; its right use was a matter of religious obligation, and the prophets and legislators always sought to secure for every Israelite family some rights in their native soil.
The selection of a legal ceremony and the stress laid upon its forms emphasise the truth that social order is the necessary basis of morality and religion. The opportunity to live healthily, honestly, and purely is an antecedent condition of the spiritual life. This opportunity was denied to slaves in the great heathen empires, just as it is denied to the children in our slums. Both here and more fully in the sections we shall deal with in the following chapters, Jeremiah shows that he was chiefly interested in the restoration of the Jews because they could only fulfil the Divine purpose as a separate community in Judah.
Moreover, to use a modern term, he was no anarchist; spiritual regeneration might come through material ruin, but the prophet did not look for salvation either in anarchy or through anarchy. While any fragment of the State held together, its laws were to be observed; as soon as the exiles were re-established in Judah, they would resume the forms and habits of an organised community. The discipline of society, like that of an army, is most necessary in times of difficulty and danger, and, above all, in the crisis of defeat.
