It shall not seem hard unto thee, when thou lettest him go free from thee; for to the double of the hire of a hireling hath he served thee six years: and Jehovah thy God will bless thee in all that thou doest.
King James Version (KJV):
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.
