10The days of our years are threescore years and ten; and if by reason of strength they be fourscore years, yet is their strength labour and sorrow; for it is soon cut off, and we fly away. 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.
