Albert Barnes Commentary 1 Kings 2:3

"and keep the charge of Jehovah thy God, to walk in his ways, to keep his statutes, [and] his commandments, and his ordinances, and his testimonies, according to that which is written in the law of Moses, that thou mayest prosper in all that thou doest, and whithersoever thou turnest thyself." — 1 Kings 2:3 (ASV)

The “statutes” have been explained to be the positive ordinances of the Law; the “commandments” the moral precepts, such as not to steal; the “judgments” the laws belonging to civil government; and the “testimonies” the laws directing the commemoration of certain events .
