15:12-18 Here the law concerning Hebrew servants is repeated. There is an addition, requiring the masters to put some small stock into their servants' hands to set up with for themselves, when sent out of their servitude, wherein they had received no wages. We may expect family blessings, the springs of family prosperity, when we make conscience of our duty to our family relations. We are to remember that we are debtors to Divine justice, and have nothing to pay with. That we are slaves, poor, and perishing. But the Lord Jesus Christ, by becoming poor, and by shedding his blood, has made a full and free provision for the payment of our debts, the ransom of our souls, and the supply of all our wants. When the gospel is clearly preached, the acceptable year of the Lord is proclaimed; the year of release of our debts, of the deliverance of our souls, and of obtaining rest in him. And as faith in Christ and love to him prevail, they will triumph over the selfishness of the heart, and over the unkindness of the world, doing away the excuses that rise from unbelief, distrust, and covetousness.

18. he hath been worth a double hired servant to thee—that is, he is entitled to double wages because his service was more advantageous to you, being both without wages and for a length of time, whereas hired servants were engaged yearly (Le 25:53), or at most for three years (Isa 16:14).
