Psalms 64:7

7And God shall shoot an arrow at them The Psalmist now congratulates himself in the confident persuasion that his prayers have not been without effect, but already answered. Though there was no appearance of God’s approaching judgment, he declares that it would suddenly be executed; and in this he affords a remarkable proof of his faith. He saw the wicked hardening themselves in their prosperity, and presuming upon impunity from the divine connivance and forbearance; but instead of yielding to discouragement, he was borne up by the belief that God, according to his usual mode of procedure with the wicked, would visit them at an unexpected moment, when they were flattering themselves with having escaped, and indulging in extravagant confidence. It is a consideration which should comfort us, when subjected to long-continued trial, that God, in delaying to punish the ungodly, does so with the express design of afterwards inflicting judgments of a more condign description upon them, and when they shall say, “Peace and safety,” overwhelming them with sudden destruction, (Jeremiah 8:11 (443))
