Psalm 90:10-16

The years of our life are seventy, or even by reason of strength eighty; yet their span is but toil and trouble; they are soon gone, and we fly away. Who considers the power of your anger, and your wrath according to the fear of you? So teach us to number our days that we may get a heart of wisdom. Return, O LORD! How long? Have pity on your servants! Satisfy us in the morning with your steadfast love, that we may rejoice and be glad all our days. Make us glad for as many days as you have afflicted us, and for as many years as we have seen evil. Let your work be shown to your servants, and your glorious power to their children.
