Adam Clarke's Bible Commentary Verse 3. If he came in by himself] If he and his wife came in together, they were to go out together: in all respects as he entered, so should he go out. This consideration seems to have induced St. Jerome to translate the passage thus: Cum quali veste intraverat, cum tali exeat. "He shall have the same coat in going out, as he had when he came in," i.e., if he came in with a new one, he shall go out with a new one, which was perfectly just, as the former coat must have been worn out in his master's service, and not his own.
Matthew Henry Commentary
Verses 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 bindin on us, yet they explain the moral law, and the rules of natura justice. The servant, in the state of servitude, was an emblem of tha state of bondage to sin, Satan, and the law, which man is brought int by robbing God of his glory, by the transgression of his precepts Likewise in being made free, he was an emblem of that liberty wherewit Christ, the Son of God, makes free from bondage his people, who ar free indeed; and made so freely, without money and without price, or free grace.
