The evident object of this law is to prevent, as far as possible, that extreme of poverty which might compel a man to sell himself in order to live. Debt is a burden in any case, to a poor man especially; but debt is the heavier burden when to the original debt is added the constant payment of interest. Hence, not merely "usury" in the modern sense of _excessive_ interest, but it is forbidden to claim or take any interest whatever from any Hebrew debtor. On the same principle, it is forbidden to take increase for food which may be lent to a poor brother; as when one lets a man have twenty bushels of wheat on condition that in due time he shall return for it twenty-two. This command is enforced (ver. 38) by reminding them from whom they have received what they have, and on what easy terms, as a gift; from their covenant God, who is Himself their security that by so doing they shall not lose: "I am the Lord your God, which brought you forth out of the land of Egypt, to give you the land of Canaan, to be your God." They need not therefore have recourse to the exaction of interest and increase from their poor brethren in order to make a living, but are to be merciful, even as Jehovah their God is merciful.
xxv. 39-55.
"And if thy brother be waxen poor with thee, and sell himself unto thee; thou shalt not make him to serve as a bondservant: as an hired servant, and as a sojourner, he shall be with thee; he shall serve with thee unto the year of jubilee: then shall he go out from thee, he and his children with him, and shall return unto his own family, and unto the possession of his fathers shall he return. For they are My servants, which I brought forth out of the land of Egypt: they shall not be sold as bondmen. Thou shalt not rule over him with rigour; but shalt fear thy God. And as for thy bondmen, and thy bondmaids, which thou shalt have; of the nations that are round about you, of them shall ye buy bondmen and bondmaids. Moreover of the children of the strangers that do sojourn among you, of them shall ye buy, and of their families that are with you, which they have begotten in your land: and they shall be your possession. And ye shall make them an inheritance for your children after you, to hold for a possession; of them shall ye take your bondmen for ever: but over your brethren the children of Israel ye shall not rule, one over another, with rigour. And if a stranger or sojourner with thee be waxen rich, and thy brother be waxen poor beside him, and sell himself unto the stranger or sojourner with thee, or to the stock of the stranger's family: after that he is sold he may be redeemed; one of his brethren may redeem him: or his uncle, or his uncle's son, may redeem him, or any that is nigh of kin unto him of his family may redeem him; or if he be waxen rich, he may redeem himself. And he shall reckon with him that bought him from the year that he sold himself to him unto the year of jubilee: and the price of his sale shall be according unto the number of years; according to the time of an hired servant shall he be with him. If there be yet many years, according unto them he shall give back the price of his redemption out of the money that he was bought for. And if there remain but few years unto the year of jubilee, then he shall reckon with him; according unto his years shall he give back the price of his redemption. As a servant hired year by year shall he be with him: he shall not rule with rigour over him in thy sight. And if he be not redeemed by these means, then he shall go out in the year of jubilee, he, and his children with him. For unto Me the children of Israel are servants; they are My servants whom I brought forth out of the land of Egypt: I am the Lord your God."
