Thou hast set our iniquities before thee - Thou hast arrayed them, or brought them forth to view, as a "reason" in thy mind for cutting us down. Death may be regarded as proof that God has brought before his mind the evidence of man's guilt, and has passed sentence accordingly. The fact of death at all; the fact that anyone of the race dies; the fact that human life has been made so brief, is to be explained on the supposition that God has arrayed before his own mind the reality of human depravity, and has adopted this as an illustration of his sense of the evil of guilt.

Our secret sins - literally, "our secret;" or, that which was concealed or unknown. This may refer to the secret or hidden things of our lives, or to what has been concealed in our own bosoms; and the meaning may be, that God has judged in the case not by external appearances, or by what is seen by the world, but by what "he" has seen in the heart, and that he deals with us according to our real character. The reference is, indeed, to sin, but sin as concealed, hidden, forgotten; the sin of the heart; the sin which we have endeavored to hide from the world; the sin which has passed away from our own recollection.

In the light of thy countenance - Directly before thee; in full view; so that thou canst see them all. In accordance with these, thou judgest man, and hence, his death.

Psalm 90:8Thou hast set our iniquities before thee - Every one of our transgressions is set before thee; noted and minuted down in thy awful register!

Our secret sins - Those committed in darkness and privacy are easily discovered by thee, being shown by the splendours of thy face shining upon them. Thus we light a candle, and bring it into a dark place to discover its contents. O, what can be hidden from the allseeing eye of God? Darkness is no darkness to him; wherever he comes there is a profusion of light - for God is light!

Thou hast set our sins before thee,.... The cause of all trouble, consumption, and death; these are before the Lord, as the evidence, according to which he as a righteous Judge proceeds; this is opposed to the pardon of sin, which is expressed by a casting it behind his back, Isaiah 38:17,

our secret sins in the light of thy countenance; the Targum and Jarchi interpret it of the sins of youth; the word is in the singular number, and may be rendered, "our secret sin" (f); which has led some to think of original sin, which is hidden from, and not taken notice of by, the greatest part of the world, though it is the source and spring of all sin. It is not unusual for the singular to be put for the plural, and may intend all such sins as are secretly committed, and not known by other men, and such as are unobserved by men themselves; as the evil thoughts of their hearts, the foolish words of their mouths, and many infirmities of life, that are not taken notice of as sins: these are all known to God, and will be brought to light and into judgment by him, and will be set in "the light of his countenance"; which denotes not a gracious forgiveness of them, but his clear and distinct knowledge of them, and what a full evidence they give against men, to their condemnation and death; and intends not only a future, but the present view the Lord has of them, and his dealings with men in life, and at death, according to them.

Thou hast set our iniquities before thee, our secret sins in the light of thy countenance.

90:8 Hast set - Thou dost observe them, as a righteous judge, and art calling us to an account for them. Secret sins - Which though hid from the eyes of men, thou hast brought to light by thy judgments.

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?
