This lengthy passage is rightly divided into two sections, one in which Moses, on behalf of the Lord commands Israel to write the law on stones as an expression of devotion as act of thanksgiving and submission to God's gracious deliverance into the Land. The boundaries that separate Israel from the world is a law, the law of God. Israel was to be a people, living in land who were marked and set apart by the righteous law of God. Not only the law, but the gospel, seen in the sacrifice upon the altar. What separates the saints from the world, law and gospel, rightly ordered, established and clung to in all covenant faithfulness. The second part is a covenant service in which Israel remembers the curses when that law and gospel are abandoned for idols.
