Therefore thou shalt keep the commandments of the Lord thy God,.... Not only because they are the commands of God, and of a covenant God and Father, which are reasons sufficient for the observance of them; but because the Lord had dealt so bountifully with them, in providing food and raiment for them in the wilderness, which always continued with them; and because, when he afflicted them, it was a fatherly chastisement, with great tenderness and compassion, and for their good; all which laid them under obligations to keep the commands of God, whatsoever he had enjoined them, whether of the moral, ceremonial, or judicial kind: to walk in his ways, and to fear him; to walk in the ways he directed, to be under an awe of his majesty, a fear of offending him, and a reverential affection for him, such as children have to a father.
