Psalms 90:9-12

For all our days are passed away in thy wrath: We bring our years to an end as a sigh. The days of our years are threescore years and ten, Or even by reason of strength fourscore years; Yet is their pride but labor and sorrow; For it is soon gone, and we fly away. Who knoweth the power of thine anger, And thy wrath according to the fear that is due unto thee? So teach us to number our days, That we may get us a heart of wisdom.
