King James Version
It shall not seem hard unto thee, when thou sendest him away free from thee; for he hath been worth a double hired servant to thee, in serving thee six years: and the LORD thy God shall bless thee in all that thou doest.English Standard Version
It shall not seem hard to you when you let him go free from you, for at half the cost of a hired servant he has served you six years. So the LORD your God will bless you in all that you do.New International Version
Do not consider it a hardship to set your servant free, because his service to you these six years has been worth twice as much as that of a hired hand. And the LORD your God will bless you in everything you do.
