Deuteronomy 32:39

Ver. 39. See now that I, even I, am he— As the great design of the separation of the Israelites from the rest of the world was, to preserve the knowledge of the true God; so, the end of all the divine chastisements upon Israel was, to shew them the folly and wickedness of idolatry, and to convince them that Jehovah alone was God: When this end was answered, the divine chastisements naturally ceased, and the Lord revisited his servants with mercy. When it is said, I kill, and I make alive, &c. the meaning is, I am to be acknowledged the author of life and death, the dispenser of prosperity and adversity, and especially the author of national changes and revolutions, whether in a way of mercy or of judgment. See 1 Samuel 2:6. Job 5:18. Hosea 6:1.Isaiah 45:7.
