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?

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."
