[9] For all our days are passed away in thy wrath: we spend our years as a tale [10] The days of our 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. [11] Who knoweth the power of thine anger? even according to thy fear, so is thy wrath. [12] So teach us to number our days, that we may apply our hearts unto wisdom.
