| Matthew Henry's Concise Commentary 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?
Pulpit CommentaryVerse 11 - Who knoweth the power of thins anger? Who can duly estimate the intensity of God's anger against such as have displeased him? Even according to thy fear, so is thy wrath; rather, or who can estimate thy fury as the fear of thee (i.e. the proper fear) requires? The verse is exegetical of ver. 9, and is intended to impress on man the terribleness of God's anger.
Gill's Exposition of the Entire BibleWho 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.
Jamieson-Fausset-Brown Bible Commentary11. 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."
