Deuteronomy 12:1

Moses now passes on to apply Deut. 12–26 the leading principles of the Decalogue to the ecclesiastical, civil, and social life of the people. Particulars will be noticed which are unique to the Law as given in Deuteronomy; and even in laws repeated from the earlier books various new circumstances and details are introduced. This is only natural. The Sinaitic legislation was nearly 40 years old and had been given under conditions of time, place, and circumstance different and distant from those now present. Yet the Sinaitic system, far from being set aside or in any way abrogated, is on the contrary throughout presupposed and assumed. Its existence and authority are taken as the starting-point for what is here prescribed, and an accurate acquaintance with it on the part of the people is taken for granted.
