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.

Who knoweth the power of thine angers - The afflictions of this life are not to be compared to the miseries which await them who live and die without being reconciled to God, and saved from their sins.

Who knoweth the power of thine anger?.... Expressed in his judgments on men: as the drowning of the old world, the burning of Sodom and Gomorrah, the consumption of the Israelites in the wilderness; or in shortening the days of men, and bringing them to the dust of death; or by inflicting punishment on men after death; they are few that take notice of this, and consider it well, or look into the causes of it, the sins of men: such as are in hell experimentally know it; but men on earth, very few closely attend to it, or rarely think of it:

even according to thy fear, so is thy wrath; or who knows thy wrath, so as to fear thee? who considers it so, as that it has such an influence upon him to fear the Lord, and stand in awe of him, and fear to offend him, and seek to please him? or rather the wrath of God is answerable to men's fear of him; and that, in some things and cases, men's fears exceed the things feared; as afflictions viewed beforehand, and death itself: the fears of them are oftentimes greater, and more distressing, than they themselves, when they come; but so it is not with the wrath of God; the greatest fears, and the most dreadful apprehensions of it, do not come up to it; it is full as great as they fear it is, and more so.

{k} Who knoweth the power of thine anger? even according to thy fear, so is thy wrath.

(k) If man's life for the shortness of it is miserable, it is even more so if your wrath is on it, as they who fear you only know.

90:11 Thy fear - According to the fear of thee; according to that fear which sinful men have of a just God. So - It bears full proportion to it, nay indeed doth far exceed it.

11. The whole verse may be read as a question implying the negative, "No one knows what Thy anger can do, and what Thy wrath is, estimated by a true piety."

90:7-11 The afflictions of the saints often come from God's love; but the rebukes of sinners, and of believers for their sins, must be seen coming from the displeasure of God. Secret sins are known to God, and shall be reckoned for. See the folly of those who go about to cover their sins, for they cannot do so. Our years, when gone, can no more be recalled than the words that we have spoken. Our whole life is toilsome and troublesome; and perhaps, in the midst of the years we count upon, it is cut off. We are taught by all this to stand in awe. The angels that sinned know the power of God's anger; sinners in hell know it; but which of us can fully describe it? Few seriously consider it as they ought. Those who make a mock at sin, and make light of Christ, surely do not know the power of God's anger. Who among us can dwell with that devouring fire?
