See, I have set before thee this day,.... Moses here returns to press the Israelites to the present observance of the laws, statutes, and judgments of one sort and another, he had been delivering to them; as being of great moment and importance to them, no other than life and good, and death and evil; which are the effects and consequences of obedience and disobedience to them; a happy temporal life, and a continuance of it in the good land of Canaan, and an enjoyment of the blessings and good things thereof to them that are obedient; for not spiritual and eternal life, or spiritual blessings and everlasting happiness, are to be had by man's obedience to the law of works, only through Christ, through his obedience, righteousness, sufferings, and death; see Gal 3:21; so temporal death, or a cutting short of natural life in the promised land, and evil things, calamities, and distresses, or a deprivation of all the good things of it to the disobedient; see Isa 1:19.
