SEV Biblia, Chapter 6:2
Para que temas al SEÑOR tu Dios, guardando todos sus estatutos y sus mandamientos que yo te mando, tú, y tu hijo, y el hijo de tu hijo, todos los días de tu vida, y que tus días sean prolongados.
Clarke's Bible Commentary - Deuteronomy 6:2
Verse 2. That thou mightest fear the Lord] Respect his sovereign authority as a lawgiver, and ever feel thyself bound to obey him. No man can walk either conscientiously or safely who has not the fear of God continually before his eyes. When this is gone, more than a guardian angel is fled. Thou, and thy son, and thy son's son] Through all thy successive generations. Whoever fears God will endeavour to bring up his children in the way of righteousness, that they also may fear God, and that pure and undefiled religion may be preserved in his family through all its generations, not only in word, but in practice also.
John Gill's Bible Commentary
Ver. 2. That thou mightest fear the Lord thy God , etc.] Being taught to know the greatness of his being, and the nature of his mind and will, and the manner of his worship; and not with a slavish fear, but with a filial one, a reverential affection for God; being instructed in their duty, as of children, to their God and Father; (see Deuteronomy 5:29) to keep all his statutes, and his commandments, which I command thee ; not in his own name, but in the name, and by the authority of God, whose minister and messenger he was; and all, having the stamp of divine authority on them, were to be observed and kept, and not one to be neglected or departed from: thou, and thy son, and thy son’s son, all the days of thy life ; a man and his children, and grandchildren; he was to take care that they kept all the commandments of the Lord as long as he lived, and had any concern with them: and that thy days may be prolonged ; long life being reckoned a very great outward mercy; a long enjoyment of, and continuance in the land of Canaan, is chiefly designed, which is usually expressed when this is observed; (see Deuteronomy 4:26,40 5:16,33).
Matthew Henry Commentary
Verses 1-3 - In this and the like passages, the "commandments" seem to denote the moral law, the "statues" the ceremonial law, and the "judgments" the law by which the judges decided. Moses taught the people all that, an that only, which God commanded him to teach. Thus Christ's minister are to teach his churches all he has commanded, neither more nor less Mt 28:20. The fear of God in the heart will be the most powerfu principle of obedience. It is highly desirable that not we only, but our children, and our children's children, may fear the Lord. Religio and righteousness advance and secure the prosperity of any people.
