11Who knoweth the power of thine anger? even according to thy fear, so is thy wrath. 12So teach us to number our days, that we may apply our hearts unto wisdom. 13Return, O LORD, how long? and let it repent thee concerning thy servants. 14O satisfy us early with thy mercy; that we may rejoice and be glad all our days.15Make us glad according to the days wherein thou hast afflicted us, and the years wherein we have seen evil. 16Let thy work appear unto thy servants, and thy glory unto their children. 17And let the beauty of the LORD our God be upon us: and establish thou the work of our hands upon us; yea, the work of our hands establish thou it.
