1. The law of God was very express, that those of their own nation should not be held in servitude above seven years, but, after they had served one apprenticeship, they should be discharged and have their liberty; yea, though they had sold themselves into servitude for the payment of their debts, or though they were sold by the judges for the punishment of their crimes. This difference was put between their brethren and strangers, that those of other nations taken in war, or bought with money, might be held in perpetual slavery, they and theirs; but their brethren must serve but for seven years at the longest. This God calls the covenant that he had made with them when he brought them out of the land of Egypt, v. 13, 14. This was the first of the judicial laws which God gave them (Exod. xxi. 2), and there was good reason for this law. (1.) God had put honour upon that nation, and he would have them thus to preserve the honour of it themselves and to put a difference between it and other nations. (2.) God had brought them out of slavery in Egypt, and he would have them thus to express their grateful sense of that favour, by letting those go to whom their houses were houses of bondage, as Egypt had been to their forefathers. That deliverance is therefore mentioned here (v. 13) as the ground of that law. Note, God's compassions towards us should engage our compassions towards our brethren; we must release as we are released, forgive as we are forgiven, and relieve as we are relieved. And this is called a covenant; for our performance of the duty required is the condition of the continuance of the favours God has bestowed.
