The new law repeatedly gives command that the debtor, who from inability to pay has become the slave of his creditor (II. 221), is not to be called upon to perform the duties of a slave, but is rather to be kept in the house as a hired servant and a serf. It requires that all slaves should participate, not only in the rest of the Sabbath, but in the enjoyment of the festivals of harvest and vintage. It repeats the command to liberate Hebrew slaves in the seventh year, and adds: "And when thou sendest him away free, thou shalt not let him go empty; thou shalt furnish him liberally out of thy flock, and out of thy floor, and out of thy winepress. Remember that thou wast a bondman in the land of Egypt, and that Jehovah thy God redeemed thee." Runaway slaves, who had escaped into another community, were not to be delivered up again to their master, according to the new code.[459] The old law gave command: "The hire of the day labourer shall not remain with thee till the morning" (II. 225). The new law requires that it shall be paid before sunset: "for he is poor, and setteth his heart upon it."[460] The poor, the widow and the orphan in the land, are not to be oppressed; they must be supported before the court, and the hand opened towards them. At the harvest there is to be no gleaning. The scattered ears are not to be gathered any more than the fallen berries in the vineyard. "Hast thou forgotten a sheaf in the field, thou shalt not return to take it; this sheaf shall be, like the gleanings, for the stranger, the widow and the orphan."[461] Strictly as the new law maintained the exclusiveness of Israel towards the neighbours (p. 221), it is equally emphatic in taking the part of the individual unprotected stranger who dwells in Israel. "Cursed is he who perverts the judgment of the stranger."[462] The law forbids the mocking of afflicted persons owing to infirmities of body; the dumb man is not to be reviled, nor a stumblingblock to be placed in the way of the blind; the man is accursed who causes a blind man to go out of his way.[463] A man shall not see the ox or sheep of his brother go astray without leading it back, or keeping it, if the owner is unknown to him; and the same shall be done with all lost property.[464] Only the young ones are to be taken from the nest of the bird, and not the mother with them.[465] Fruit trees are to be spared even in the land of an enemy.[466] The mouth of the thrashing-ox is not to be tied, and even animals must rest on the Sabbath.[467]
