Psalms 90: 3 - 6, 12 - 13, 14 - 17
3 Thou turnest man back to the dust, and sayest, "Turn back, O children of men!"
4 For a thousand years in thy sight are but as yesterday when it is past, or as a watch in the night.
5 Thou dost sweep men away; they are like a dream, like grass which is renewed in the morning:
6 in the morning it flourishes and is renewed; in the evening it fades and withers.
12 So teach us to number our days that we may get a heart of wisdom.
13 Return, O LORD! How long? Have pity on thy servants!
14 Satisfy us in the morning with thy steadfast love, that we may rejoice and be glad all our days.
15 Make us glad as many days as thou hast afflicted us, and as many years as we have seen evil.
16 Let thy work be manifest to thy servants, and thy glorious power to their children.
17 Let the favor 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.
