Law of Moses is the whole body of the Mosaic legislation (1 Kings 2:3; 2 Kings 23:25; Ezra 3:2). It is called by way of eminence simply "the Law" (Heb. Torah, Deuteronomy 1:5; Deuteronomy 1:4, Deuteronomy 1:4; Deuteronomy 1:17, Deuteronomy 1:17; Deuteronomy 1:27, Deuteronomy 1:27). As a written code it is called the "book of the law of Moses" (2 Kings 14:6; Isaiah 8:20), the "book of the law of God" (Joshua 24:26).
The great leading principle of the Mosaic law is that it is essentially theocratic; i.e., it refers at once to the commandment of God as the foundation of all human duty.
