Psalms 90:8

8Thou hast set our iniquities before thee. To show that by this complaint he is far from intending to murmur against God, he asserts that the Divine anger, however terrible it had been, was just, inasmuch as the people had provoked it by their iniquities; for those who, when stricken by the Divine hand, are not brought to genuine humiliation, harden themselves more and more. The true way to profit, and also to subdue our pride, is to feel that He is a righteous judge. Accordingly Moses, after having briefly taught that men by nature vanish away like smoke, gathers from thence that it is not to be wondered at if God exanimates and consumes those whom he pursues with his wrath. The manner of the expression by which God is described as showing the tokens of his anger is to be observed — he sets the iniquities of men before his eyes Hence it follows, that whatever intermission of punishment we experience ought in justice to be ascribed to the forbearance of. God, who buries our sins that he may spare us. The word עלומים, alumim, which I have rendered our secret sins, is translated by some, our youth; (567) as if Moses had said that the faults committed in youth are brought to remembrance. But this is too forced, and inconsistent with the scope of the passage; for it would destroy the contrast between secret sins and the light of God’s countenance, by which Moses intimates that men hide themselves in darkness, and wrap themselves in many deceits, so long as God does not shine upon them with the light of his judgment; whereas, when he draws them back from their subterfuges, by which they endeavor to escape from him, and sets before his eyes the sins which they hide by hypocrisy, being subdued by fear and dread, they are brought sincerely to humble themselves before him.
