Deuteronomy 4:24 - Joseph Benson’s Commentary on the Old and New Testaments

A consuming fire A just and terrible God, who, notwithstanding his special relation to you, will severely punish you, if you provoke him. A jealous God Who, being espoused to you, will be highly incensed against you if you follow after other lovers, or commit whoredom (so to speak) with idols, and will bear no rival or partner.
