Psalms 51:13 - Joseph Benson’s Commentary on the Old and New Testaments

Then will I teach transgressors thy way Thy will and their duty, and the way to eternal happiness; or, rather, the manner of thy dealing with sinners, whom thou dost so severely chastise for their sins, and yet so graciously receive to mercy upon their repentance. Both which I will show them in my own example, for I will make known unto them my fall and recovery, through thy grace, although I shall thereby publish, not only thy goodness, but my own shame, which I shall most willingly bear, that I may, in some measure, repair the injury which I have done to thy cause and to my fellow-creatures, by my public and scandalous crimes. And sinners shall be converted unto thee I persuade myself that my endeavours shall not want success; and that either thy justice and severity on the one hand, or thy goodness and clemency on the other, will bring some sinners to repentance. Certainly, as Dr. Delaney observes in this verse, this instance of David's miserable fall and happy restoration is well “fitted to mortify the vanity and merit of human virtue, and to raise the power and price of humble penitence, to abate the pride of self-sufficiency, and support the hope of frailty! Who can confide in his own strength when he sees a David fall? Who can despair of divine mercy when he sees him forgiven? Sad triumph of sin over all that is great and excellent in man! Glorious triumph of repentance over all that is shameful and dreadful in sin!” Book 4. chap. 24.
