George Haydock's Catholic Commentary
Psalms 6:11
Troubled. This is a prophecy, (St. Augustine) or a prayer for their speedy and earnest conversion, (St. Jerome; Calmet) or a threat if they persist. (Worthington) --- Speedily. At the last day, the wicked will perceive how short life has been. Tunc sentient peccatores quam non sit longa omnis vita quæ transit. (St. Augustine)
