See, I have set before thee this day life and good, and death and evil;

Jamieson-Fausset-Brown Bible Commentary

De 30:15-20. Death and Life Are Set before the Israelites.

15-20. See, I have set before thee this day life and good, and death and evil-the alternative of a good and happy, or a disobedient and miserable life. Love of God and compliance with His will are the only ways of securing the blessings and avoiding the evils described. The choice was left to them, and in urging upon them the inducements to a wise choice, Moses warmed as he proceeded into a tone of solemn and impressive earnestness similar to that of Paul to the elders of Ephesus (Ac 20:26, 27).

Matthew Henry's Concise Commentary

30:15-20 What could be said more moving, and more likely to make deep and lasting impressions? Every man wishes to obtain life and good, and to escape death and evil; he desires happiness, and dreads misery. So great is the compassion of the Lord, that he has favoured men, by his word, with such a knowledge of good and evil as will make them for ever happy, if it be not their own fault. Let us hear the sum of the whole matter. If they and theirs would love God, and serve him, they should live and be happy. If they or theirs should turn from God, desert his service, and worship other gods, that would certainly be their ruin. There never was, since the fall of man, more than one way to heaven; which is marked out in both Testaments, though not with equal clearness. Moses meant that same way of acceptance, which Paul more plainly described; and Paul's words mean the same obedience, on which Moses more fully treated. In both Testaments the good and right way is brought near, and plainly revealed to us.
