Deuteronomy 15:12-14

When thy brother a Hebrew man, or Hebrew woman is sold to thee, and hath served thee six years, in the seventh year thou shalt let him go free:

And when thou sendest him out free, thou shalt not let him go away empty:

But shall give him for his way out of thy flocks, and out of thy barnfloor, and thy winepress, wherewith the Lord thy God shall bless thee.
