10Our days may come to seventy years, or eighty, if our strength endures; yet the best of them are but trouble and sorrow, for they quickly pass, and we fly away. 11If only we knew the power of your anger! Your wrath is as great as the fear that is your due. 12Teach us to number our days, that we may gain a heart of wisdom. 13Relent, Lord! How long will it be? Have compassion on your servants. 14Satisfy us in the morning with your unfailing love, 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 trouble. 16May your deeds be shown to your servants, your splendor to their children. 17May the favor#90:17 Or beauty of the Lord our God rest on us; establish the work of our hands for us— yes, establish the work of our hands.
