Deuteronomy 6:20

(20) What mean the testimonies, and the statutes, and the judgments.—These three words appear for the first time together in the introduction to this discourse (Deuteronomy 4:45). The Law, or Torah, includes charges, and institutions, and requirements. The Decalogue itself is primarily the Torah; the charge which follows may come under the head of “testimony.” The “statutes” and “judgments” more properly describe the contents of the chapters from Deuteronomy 11-26 inclusive.
