Psalm 90:10-13

The days of our years are threescore years and ten; And if by reason of strength they be fourscore years, Yet is their strength labour and sorrow; For it is soon cut off, and we fly away. Who knoweth the power of thine anger? Even according to thy fear, so is thy wrath. So teach us to number our days, That we may apply our hearts unto wisdom. Return, O LORD, how long? And let it repent thee concerning thy servants.
