Psalm 90 meditations

This is not just because of the "New Year", but more what I have been mulling over for a while now...

1 Lord, You have been our dwelling place in all generations.
2 Before the mountains were brought forth,
Or ever You had formed the earth and the world,
Even from everlasting to everlasting, You are God.

10 The days of our lives are seventy years;
And if by reason of strength they are eighty years,
Yet their boast is only labor and sorrow;
For it is soon cut off, and we fly away.
11 Who knows the power of Your anger?
For as the fear of You, so is Your wrath.
12 So teach us to number our days,
That we may gain a heart of wisdom.
