Psalms 90:11

Who knoweth the power of thine anger? The greatness, and force, and dreadful effects of thine anger, conceived against the sons of men, and in particular against thine own people, for their sins? Few or none sufficiently apprehend it, or steadfastly believe it, or duly consider it, or are rightly affected with it: all which particulars are comprehended under this word knoweth. Even according to thy fear, so is thy wrath That is, as some interpret the words, “In proportion to the fear and reverence which are due to thee as the great Lord and Sovereign of the world, so may the transgressors of thy law expect their punishment.” Or, according to the fear and dread which sinful men have, or ought to have, of thee, a just and holy God, so is thy wrath. It bears full proportion to it, nay, indeed, far exceeds it. These fears of thee are not groundless apprehensions, the effects of ignorance and folly, or of superstition, as heathen and infidels have sometimes said, but are just, and built on solid grounds, and justified by the terrible effects of thy wrath upon ungodly men. Nor can it be ever said of thy wrath, as it is often said of death, that the fear of it is worse than the thing itself. Houbigant renders the words thus: Who knoweth, or considereth, the power of thine anger; and thy wrath, in proportion as thou art terrible? That is, in other words, “Notwithstanding all the manifestations of thine indignation against sin, which introduced death and every other calamity among men, who is there that knoweth, who that duly considereth and layeth to heart, the almighty power of that indignation?” Something seems evidently intimated here beyond the punishments of sin in this world; for these are what men feel and experience. But who knows the dreadful punishments of a future world? Well, therefore, is this reflection followed by a devout prayer in the next verse. For the knowledge and consideration here intended are the gift of God.
