Deuteronomy 15:15
King James Version
“And thou shalt remember that thou wast a bondman in the land of Egypt, and the LORD thy God redeemed thee: therefore I command thee this thing to day.”
Context
12if 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: wherewith the LORD thy God hath blessed thee thou shalt give unto him.
15And thou shalt remember that thou wast a bondman in the land of Egypt, and the LORD thy God redeemed thee: therefore I command thee this thing to day.
16And it shall be, if he say unto thee, I will not go away from thee; because he loveth thee and thine house, because he is well with thee;
17Then thou shalt take an aul, and thrust through his ear unto the door, and he shall be thy servant for ever. And also unto thy maidservant thou shalt do likewise.
18It shall not seem hard unto thee, when thou sendest him away free from thee; for he hath been worth a double hired servant in serving thee six years: and the LORD thy God shall bless thee in all that thou doest.
