Psalms 90:11

Who knoweth the power of thine anger? - Who can measure it, or take a correct estimate of it, as it is manifest in cutting down the race of people? If the removal of people by death is to be traced to thine anger - or is, in any proper sense, an expression of thy wrath - who can measure it, or understand it? The cutting down of whole generations of people - of nations - of hundreds of million of human beings - of the great, the powerful, the mighty, as well as the weak and the feeble, is an amazing exhibition of the “power” - of the might - of God; and who is there that can fully understand this? Who can estimate fully the wrath of God, if this is to be regarded as an expression of it? Who can comprehend what this is? Who can tell, after such an exhibition, what may be in reserve, or what further and more fearful displays of wrath there may yet be?

Even according to thy fear, so is thy wrath - literally, “And according to thy fear, thy wrath.” The word rendered “fear” would here seem to refer to the “reverence” due to God, or to what there is in his character to inspire awe: to wit, his power, his majesty, his greatness; and the sense seems to be that his wrath or anger as manifested in cutting down the race seems to be commensurate with all in God that is vast, wonderful, incomprehensible. As no one can understand or take in the one, so no one can understand or take in the other. God is great in all things; great in himself; great in his power in cutting down the race; great in the expressions of his displeasure.
