2 "When you buy a Hebrew slave, he will serve six years. The seventh year he goes free, for nothing. 3 If he came in single he leaves single. If he came in married he leaves with his wife. 4 If the master gives him a wife and she gave him sons and daughters, the wife and children stay with the master and he leaves by himself.
Matthew Henry's Commentary on Exodus 21:2-4
Commentary on Exodus 21:1-11
(Read Exodus 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.
