"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.
Who knows the power of Your anger?
For as the fear of You, so is Your wrath.
So teach us to number our days,
That we may gain a heart of wisdom." - Psalm 90:10-12
