12 So teach us to count our days
   that we may gain a wise heart.


13 Turn, O Lord! How long?
   Have compassion on your servants!
14 Satisfy us in the morning with your steadfast love,
   so that we may rejoice and be glad all our days.
15 Make us glad for as many days as you have afflicted us,
   and for as many years as we have seen evil.
16 Let your work be manifest to your servants,
   and your glorious power to their children.
17 Let the favour of the Lord our God be upon us,
   and prosper for us the work of our hands—
   O prosper the work of our hands!
