5. On this side Jordan, in the land of Moab, began Moses to declare this law--that is, explain this law. He follows the same method here that he elsewhere observes; namely, that of first enumerating the marvellous doings of God in behalf of His people, and reminding them what an unworthy requital they had made for all His kindness--then he rehearses the law and its various precepts.
