Psalms 51:13

Having experienced the joy of penitence and restoration, he will endeavour to instruct transgressors in the ways of Jehovah in which they have refused to walk (Isaiah 42:24), those commandments which they have refused to keep, so that they may return to Him from Whom they have gone astray. Psalms 32 has been thought to be the fulfilment of this resolution. This resolve is however, it is said, "little appropriate to David, whose natural and right feeling in connexion with his great sin must rather have been that of silent humiliation than of an instant desire to preach his forgiveness to other sinners." But surely an endeavour to undo the evil effects of a sin whereby he "had given great occasion to the enemies of the Lord to blaspheme" would be one of the most fitting fruits of repentance.
