Romans 7:12

Therefore the law is holy
This is a conclusion or inference drawn from the preceding discourse, in commendation of the law; that standing clear of any charge or imputation of sin, as being the cause of it. This epithet the apostle gives to the law is what the Jews frequently give it; worthy are the Israelites, say they ^F8,

``to whom is given (avydq atyyrwa) "the holy law"; in which they study day and night.''

the commandment,
either the same, or everyone of the commandments in particular, and especially that which is cited, "thou shall not covet". Some have thought that the three properties of it design the threefold division of the law; and suppose that by that which is "holy" is meant the ceremonial law, which sanctified to the purifying of the flesh; by that which is "just", the judicial law, which pointed out to the Jewish commonwealth what was right and wrong; and by that which is "good", the moral law in all its precepts: but nothing is more certain, than that the moral law is only spoken of in this context, which may be said to be

holy,
because of its author, the holy God, from whom nothing can come but what is holy; and because of the matter of it, it is a transcript of the holy nature of God, a declaration of his holy will; it requires holiness both of heart and life; it forbids whatever is unholy, and commands nothing but what is holy; it teaches men to live holy, sober, righteous, and godly lives. It may be truly called

just,
or righteous, as it demands perfect obedience to all its precepts, or it will not admit of it as a righteousness; as it pronounces guilty, curses and condemns for every disobedience of it; as it deals impartially with persons the transgressors of it; and as it acquits believers upon the foot of the righteousness of Christ, the fulfilling end of it. It is rightly called

good,
from the author of it, God, from whom every good thing comes, and nothing else; from the matter of it, and from the use of it both to saints and sinners.
