The commandments of God are perhaps the most well-known portion of the Law, likely because they are the type of Law to which the Bible most often refers, especially in the New Covenant. Let us first look at the definition of "commandment:"
"The Hebrew word "mitsvah" comes from a primitive root, "tsavah" meaning "to command." It has to do with giving charge, or ordering something to be done. Mitsvot (plural) are action-based. A commandment is something that is to be done, having been ordered by Yahweh."
This Hebrew word is first mentioned in respect to Abraham—Yahweh stated that he kept, among other things, "His commandments" (Gen. 26:5). Most often the word is used as an inclusive term for all the different portions of the Law:
and if you shall reject my statutes, and if your soul abhors my ordinances, so that you will not do all my commandments, but break my covenant; (Leviticus 26:15)
Thus, in one sense, anything God commands in His Law can be considered a commandment. However, sometimes what God commands is specifically seen as a commandment and nothing else. Let us look at those specific items in the Law termed "commandments" as well as those items that God commanded His people that are not termed ordinances, statutes or laws.
13This is the end of the matter. All has been heard. Fear God, and keep his commandments; for this is the whole duty of man. 14For God will bring every work into judgment, with every hidden thing, whether it is good, or whether it is evil. (Ecclesiastes 12:13-14)
