24:10-15 It is well, when a man has sinned, if he has a heart within to smite him for it. If we confess our sins, we may pray in faith that God would forgive them, and take away, by pardoning mercy, that sin which we cast away by sincere repentance. What we make the matter of our pride, it is just in God to take from us, or make bitter to us, and make it our punishment. This must be such a punishment as the people have a large share in, for though it was David's sin that opened the sluice, the sins of the people all contributed to the flood. In this difficulty, David chose a judgment which came immediately from God, whose mercies he knew to be very great, rather than from men, who would have triumphed in the miseries of Israel, and have been thereby hardened in their idolatry. He chose the pestilence; he and his family would be as much exposed to it as the poorest Israelite; and he would continue for a shorter time under the Divine rebuke, however severe it was. The rapid destruction by the pestilence shows how easily God can bring down the proudest sinners, and how much we owe daily to the Divine patience.

2Sa 24:10-14. He, Having Three Plagues Propounded by GAD, Repents, and Chooses Three Days' Pestilence.

10-13. David's heart smote him after that he had numbered the people. And David said unto the Lord, I have sinned—The act of numbering the people was not in itself sinful; for Moses did it by the express authority of God. But David acted not only independently of such order or sanction, but from motives unworthy of the delegated king of Israel; from pride and vainglory; from self-confidence and distrust of God; and, above all, from ambitious designs of conquest, in furtherance of which he was determined to force the people into military service, and to ascertain whether he could muster an army sufficient for the magnitude of the enterprises he contemplated. It was a breach of the constitution, an infringement of the liberties of the people, and opposed to that divine policy which required that Israel should continue a separate people. His eyes were not opened to the heinousness of his sin till God had spoken unto him by His commissioned prophet.
