Commenting on Psalm 90:1-17
This mortality is not accidental, neither was it inevitable in the original of our nature, but sin has provoked the Lord to anger, and therefore thus we die. For we are consumed by thine anger. This is the scythe which mows and the scorching heat which withers.
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.
