Charles Ellicott Commentary 2 Chronicles 19:10

"And whensoever any controversy shall come to you from your brethren that dwell in their cities, between blood and blood, between law and commandment, statutes and ordinances, ye shall warn them, that they be not guilty towards Jehovah, and so wrath come upon you and upon your brethren: this do, and ye shall not be guilty." — 2 Chronicles 19:10 (ASV)

And. — Namely.

Cause. — Rîbh, “controversy” (2 Chronicles 19:8).

Shall come to you. — That is, be referred to you as the Supreme Court of Appeal.

Of. — From your brethren — that is, not your judicial brethren, but your fellow countrymen.

That dwell in their cities. — In the various country towns, as opposed to the capital.

Between blood and blood. — See Deuteronomy 17:8. Questions growing out of cases of homicide—for example, whether a given crime were murder or manslaughter.

Between law and commandment, statutes and judgments. — That is, questions about the interpretation and application of the different legal rules and principles. The phrase “commandment, statutes, and judgments,” is a sort of summary of the various kinds of law.

You shall even warn them that they do not trespass. — Then you shall instruct them in order that they do not trespass.

Warn. — Teach (Exodus 18:20) them the true sense and bearing of the law in the particular case.

Trespass. — Incur guilt; by giving false judgment.

And so wrath (2 Chronicles 19:2) ... brethren. — The miscarriage of justice would involve not only the immediate agents, but the whole people, in guilt and its penal consequences.

This do ... trespass. — Thus shall you do (2 Chronicles 19:9), that you may not incur guilt.
