You have set our iniquities before you, our secret sins in the light of your presence.
Moses opens by anchoring the people to God's covenant favor before he addresses their misery and judgment. He means to say: yes, you die like all men, yes, God punishes sin, but He has adopted you, and that peculiar grace is your true dwelling place through all generations.

Commenting on Psalm 90:1-17
Thou hast set our iniquities before thee. Hence these tears! Sin seen by God must work death; it is only by the covering blood of atonement that life comes to any of us. When God was overthrowing the tribes in the wilderness he had their iniquities before him, and therefore dealt with them in severity. He could not have their iniquities before him and not smite them.
Moses had, in the foregoing verses, lamented the frailty of human life in general; the children of men are as a sleep and as the grass. But here he teaches the people of Israel to confess before God that righteous sentence of death which they were under in a special manner, and which by their sins they had brought upon themselves.
