The same doctrine Moses repeated in his ministry. For he also inculcated the same precepts upon which the covenant of works had been built: he both repeated the same solemn saying, He who doeth these things shall live in them, Lev. 18:5 and also added another, Cursed be he who shall not perform the words of this law in doing them, Deut. 27:26. That this is the curse of the law, as it stands opposed to the covenant of grace, Paul teacheth, Gal. 3:10. which, however, is not so to be understood, as if God had intended, by the ministry of Moses, to make a new covenant of works with Israel, with a view to obtain righteousness and salvation by such a covenant. But that repetition of the covenant of works was designed to convince the Israelites of their sin and misery, to drive them out of themselves, to teach them the necessity of a satisfaction, and to compel them to cleave to Christ: and thus it was subservient to the covenant of grace, Rom. 10:4.
