Who knoweth the power of thine anger? even according to thy fear, so is thy wrath.
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
Who knoweth the power of thine anger? Moses saw men dying all around him: he lived among funerals, and was overwhelmed at the terrible results of the divine displeasure. He felt that none could measure the might of the Lord's wrath. Even according to thy fear, so is thy wrath.
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.
