21:1 The first verse is the general title of the laws contained in this and the two following chapter s. Their government being purely a theocracy; that which in other states is to be settled by human prudence, was directed among them by a divine appointment. These laws are called judgments; because their magistrates were to give judgment according to them. In the doubtful cases that had hitherto occurred, Moses had particularly enquired of God, but now God gave him statutes in general, by which to determine particular cases. He begins with the laws concerning servants, commanding mercy and moderation towards them. The Israelites had lately been servants themselves, and now they were become not only their own matters, but masters of servants too; lest they should abuse their servants as they themselves had been abused, provision was made for the mild and gentle usage of servants.
21:1-11 The laws in this chapter relate to the fifth and sixth commandments; and though they differ from our times and customs, nor are they binding on us, yet they explain the moral law, and the rules of natural justice. The servant, in the state of servitude, was an emblem of that state of bondage to sin, Satan, and the law, which man is brought into by robbing God of his glory, by the transgression of his precepts. Likewise in being made free, he was an emblem of that liberty wherewith Christ, the Son of God, makes free from bondage his people, who are free indeed; and made so freely, without money and without price, of free grace.
