It shall not seem hard to thee when thou sendest him away free from thee,.... He should not grudge him his liberty, nor what he gives to him when he dismisses him: for he hath been worth a double hired servant to thee in serving thee six years; since a hired servant a man is obliged to pay him wages for his work, besides his food, whereas a bondservant received no wages. Aben Ezra remarks, that this proves that a man might not hire himself for more than three years; or however, whereas a hired servant was sometimes hired for so many years, and this is the longest time of any we read of, a servant serving his master six years, his service must be worth double the service of an hired servant, which at most was but three years: and the Lord thy God shall bless thee in all thou doest; thus well using thy servants, whether menservants or maidservants.
