As all work must cease on the seventh day, the day of Jehovah, so must there be a similar cessation in the seventh year, which is therefore called the Sabbath year. In every seventh year the Israelites were to allow the land which Jehovah had let to them to lie fallow, in honour of the real owner. In this year the land was not sowed, nor the vine-trees cut, nor the wild beast driven from the field, every one must seek on the fallow what had grown there without culture. If this Sabbath of the seventh year was kept Jehovah would send such increase on the preceding sixth year that there should be no want.[406] When this period of seven fallow years had occurred seven times the circle appeared to be complete, and from this point of view the law ordained that at such a time everything should return to the original position. Hence, when the seventh Sabbath year was seven times repeated (in the year of Jubilee) not only was agriculture stopped, but all alienated property, with the buildings and belongings, went back to the original owner or his heirs.[407] The consequence was that properties were never really sold, but the use of them was assigned to others, and hence, even before the year of Jubilee, the owner could redeem his land by paying the value of the produce which would be yielded before the year of Jubilee. But the priests were far from being able to carry out these extended requirements which proceeded from the sanctity of the Sabbath, and from the conception that the land of Israel belonged to Jehovah, and every family held their property from Jehovah himself, and which were intended to make plain the true nature of the property of the Israelites. It was an ideal picture which they set up, and hardly so much as an attempt was made to carry it out. They could reckon with more certainty on obedience to a law which ordained that no interest was to be taken from the poor, and no poor man's mantle was to be taken in pledge.[408] Nevertheless, the law of debt was severe. If the debtor could not pay his debt before a fixed time the creditor was allowed to pay himself with the moveable and fixed property of the debtor; he could sell his wife and children, and even the debtor himself, as slaves, or use him as a slave in his own service.
