The covenant was national, and therefore embraced all the elements which make up the nation. The "little ones" would of course be represented by their parents or guardians; the absent Deuteronomy 29:15 by those present; nor were the servants and proselytes to be excluded (compare Acts 2:39). The text is fairly alleged in justification of the Church's practice of admitting little ones into covenant with God by Baptism, and accepting promises made on their behalf by sponsors.

Your little ones, your wives,.... Who are scarce ever mentioned in any special law or solemn transaction:

and thy stranger that is in thy camp; not only the proselyte of righteousness, who embraced the Jewish religion entirely, but the proselyte of the gate, who was admitted to dwell among them, having renounced idolatry. These standing with the Israelites, when this covenant was made, has respect to the Gentiles, who as well as the Jews have an interest in the covenant of grace made with Christ; in whom there is, neither Jew nor Gentile, any difference between them:

from the hewer of thy wood to the drawer of thy water; that hewed wood for firing and other uses, and drew water for the camp; who were generally mean persons, and perhaps some that came out of Egypt with them are here intended; however, mean and abject persons are meant, and signifies that none should be excluded from a concern in this solemn affair on account of their meanness.

The covenant of the Lord embraced, however, not only the men of Israel, but also the wives and children, and the stranger who had attached himself to Israel, such as the Egyptians who came out with Israel (Exodus 12:38; Numbers 11:4), and the Midianites who joined the Israelites with Hobab (Numbers 10:29), down to the very lowest servant, "from thy hewer of wood to thy drawer of water" (cf. Joshua 9:21, Joshua 9:27).

Your little ones, your wives, and thy stranger that is in thy camp, from the hewer of thy wood unto the drawer of thy water:

29:11 Thy stranger - Such strangers as had embraced their religion: all sorts of persons, yea, even the meanest of them.

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.
