Deuteronomy 15:12-14

12And if thy brother, an Hebrew man, or an Hebrew woman, be sold unto thee, and serve thee six years; then in the seventh year thou shalt let him go free from thee. 13And when thou sendest him out free from thee, thou shalt not let him go away empty: 14Thou shalt furnish him liberally out of thy flock, and out of thy floor, and out of thy winepress: of that wherewith Yhwh thy God hath blessed thee thou shalt give unto him.
