Ut timeas Jehovam Deum tuum, custodiendo omnia statuta ejus et praecepta ejus, quae ego praecipio tibi, tu et filius tuus, et filius tilii tui, omnibus diebus vitae tuae: et ut prolongentur dies tui.

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 endeavor 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.

That thou mayest (a) fear the LORD thy God, to keep all his statutes and his commandments, which I command thee, thou, and thy son, and thy son's son, all the days of thy life; and that thy days may be prolonged.
(a) A reverent face and love for God is the first beginning to keeping God's commandments.

That thou mightest fear the Lord thy God,.... 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.

The reason for communicating the law was to awaken the fear of God (cf. Deuteronomy 4:10; Deuteronomy 5:26), and, in fact, such fear of Jehovah as would show itself at all times in the observance of every commandment. "Thou and thy son:" this forms the subject to "thou mightest fear," and is placed at the end for the sake of emphasis. The Hiphil האריך has not the transitive meaning, "to make long," as in Deuteronomy 5:30, but the intransitive, to last long, as in Deuteronomy 5:16; Exodus 20:12, etc.
