“For we have been consumed by Your anger, and by Your wrath we are terrified. You have set our iniquities before You, our secret sins in the light of Your countenance. For all our days have passed away in Your wrath; we finish our years like a sigh. The days of our lives are seventy years; and if by reason of strength they are eighty years, yet their boast is only labor and sorrow; for it is soon cut off, and we fly away.” Psalm 90:7-10.
