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, Deut. 1:5; 4:8, 44; 17:18, 19; 27:3, 8).
As a written code it is called the "book of the law of Moses" (2
Kings 14:6; Isa. 8:20), the "book of the law of God" (Josh.
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.
