Второзаконие 5:21

A. The True Essence of the Law and Its Fulfilment The exposition of the law commences with a repetition of the ten words of the covenant, which were spoken to all Israel directly by the Lord Himself.

In this chapter we have the second edition of the ten commandments. I. The general intent of them; they were in the nature of a covenant between God and Israel (Deu 5:1-5). II. The particular precepts are repeated (v. 6-21), with the double delivery of them, both by word and writing (Deu 5:22). III. The settling of the correspondence thenceforward between God and Israel, by the mediation and ministry of Moses. 1. It was Israel's humble petition that it might be so (Deu 5:23-27). 2. It was God's gracious grant that it should be so (Deu 5:28-31). And hence he infers the obligation they were under to obedience (Deu 5:32, Deu 5:33).

5:21 covet: This commandment differs from the others because it pertains to a desire rather than to an act. An evil desire is no less offensive to God than an evil deed (see Matt 5:27-28).
