(13) That he may establish thee to day for a people unto himself.--It must be carefully observed that this is the aspect of the covenant which makes Jehovah responsible for the fulfilment of the whole. "He takes all this trouble for the sake of establishing thee in His presence for a people" (Rashi). The people's part, as described in this verse, is only to accept the position. And thus the covenant of Deuteronomy 29 is brought into the closest similarity with that which is called the New Covenant in Jeremiah 31:31, Hebrews 8:8; the form of which is "I will" be to them a God, and "they shall" be to me a people. God undertakes for the people's part of the covenant as well as His own. In Deuteronomy the first half of the New Covenant appears here in Deuteronomy 29, "that He may be unto thee a God." The second part appears in Deuteronomy 30:6-8, "The Lord thy God will circumcise thy heart . . . to love the Lord thy God."
29:10-21 The national covenant made with Israel, not only typified the covenant of grace made with true believers, but also represented the outward dispensation of the gospel. Those who have been enabled to consent to the Lord's new covenant of mercy and grace in Jesus Christ, and to give up themselves to be his people, should embrace every opportunity of renewing their open profession of relation to him, and their obligation to him, as the God of salvation, walking according thereto. The sinner is described as one whose heart turns away from his God; there the mischief begins, in the evil heart of unbelief, which inclines men to depart from the living God to dead idols. Even to this sin men are now tempted, when drawn aside by their own lusts and fancies. Such men are roots that bear gall and wormwood. They are weeds which, if let alone, overspread the whole field. Satan may for a time disguise this bitter morsel, so that thou shalt not have the natural taste of it, but at the last day, if not before, the true taste shall be discerned. Notice the sinner's security in sin. Though he hears the words of the curse, yet even then he thinks himself safe from the wrath of God. There is scarcely a threatening in all the book of God more dreadful than this. Oh that presumptuous sinners would read it, and tremble! for it is a real declaration of the wrath of God, against ungodliness and unrighteousness of man.
That be may establish thee this day for a people unto himself, and that he may be unto thee a God,.... Which contains the sum and substance of the covenant; see Jeremiah 32:38,
as he hath said unto thee, and as he had sworn unto thy fathers, to Abraham, to Isaac, and to Jacob; Deuteronomy 26:17.
