Psalms 90: 2 - 5, 12 - 14, 16
2 Before the mountains were brought forth, or ever thou hadst formed the earth and the world, from everlasting to everlasting thou art God.
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:
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.
16 Let thy work be manifest to thy servants, and thy glorious power to their children.
