12So teach us to number our days, that we may present a heart of wisdom. 13Return, O LORD! How long will it be? Have compassion on Your servants. 14Satisfy us in the morning with Your loving devotion, that we may sing for joy and be glad all our days. 15Make us glad for as many days as You have afflicted us, for as many years as we have seen evil. 16May Your work be shown to Your servants, and Your splendor to their children. 17May the favor of the Lord our God rest upon us; establish for us the work of our hands— yes, establish the work of our hands!
