Leviticus 25:39

And if thy brother that dwelleth by thee be waxen poor, and be sold unto thee; thou shalt not compel him to serve as a bondservant:

"'If your brother has grown poor among you, and sells himself to you; you shall not make him to serve as a slave.

And if thy brother be waxed poor with thee, and sell himself unto thee; thou shalt not make him to serve as a bond-servant.

`And when thy brother becometh poor with thee, and he hath been sold to thee, thou dost not lay on him servile service;

If a countryman among you becomes destitute and sells himself to you, then you must not force him into slave labor.
