Deuteronomy 32:4 - Joseph Benson’s Commentary on the Old and New Testaments

He is a rock Stable in his nature, invincible in his power, fixed and immutable in his counsels, promises, and ways; so that if there should be a sad change in your affairs, remember that this proceeds from yourselves, and from the change of your ways toward God, and not from God, with whom is no variableness nor shadow of turning, James 1:17. His work is perfect All his works, whether of creation, providence, or grace, and all his actions are unblameable, perfect, wise, and righteous. All his ways are judgment His dealings with you his people, and his administrations in the world toward all mankind, are just and holy in the highest degree. A God of truth Ever faithful and constant to his promises. This seems to be mentioned in opposition to the infidelity and inconstancy of Israel, which he speaks of afterward. And with out iniquity Although we are often ignorant of the methods and reasons of the divine procedure, yet it is as impossible there should be injustice or iniquity in God, as that infinite and unchangeable wisdom should act foolishly, or essential goodness should degenerate into malice, or, in the Scripture language, that light should become darkness. Just and right is he Righteous in all that he doth. How should he do wrong, all whose actions are necessarily founded on perfect and immutable wisdom, justice, and equity?
