Psalm 90 seems to be about the brevity and transience of human life in contrast to God's eternity:
[Psa 90:1-17 ASV] (1) A Prayer of Moses the man of God. Lord, thou hast been our dwelling-place In all generations. (2) Before the mountains were brought forth, Or ever thou hadst formed the earth and the world, Even from everlasting to everlasting, thou art God. (3) Thou turnest man to destruction, And sayest, Return, ye children of men. (4) For a thousand years in thy sight Are but as yesterday when it is past, And as a watch in the night. (5) Thou carriest them away as with a flood; they are as a sleep: In the morning they are like grass which groweth up. (6) In the morning it flourisheth, and groweth up; In the evening it is cut down, and withereth. (7) For we are consumed in thine anger, And in thy wrath are we troubled. (8) Thou hast set our iniquities before thee, Our secret sins in the light of thy countenance. (9) For all our days are passed away in thy wrath: We bring our years to an end as a sigh. (10) The days of our years are threescore years and ten, Or even by reason of strength fourscore years; Yet is their pride but labor and sorrow; For it is soon gone, and we fly away. (11) Who knoweth the power of thine anger, And thy wrath according to the fear that is due unto thee? (12) So teach us to number our days, That we may get us a heart of wisdom. (13) Return, O Jehovah; how long? And let it repent thee concerning thy servants. (14) Oh satisfy us in the morning with thy lovingkindness, That we may rejoice and be glad all our days. (15) Make us glad according to the days wherein thou hast afflicted us, And the years wherein we have seen evil. (16) Let thy work appear unto thy servants, And thy glory upon their children. (17) And 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.
Is Moses anticipating life after this vale of tears, living in God's eternal heavenly house?
Or is he anticipating God to turn the tide of history? Is he saying "You've been faithful to come through, turning our difficult times into satisfying results"?
If resurrection and everlasting life in God's heavenly home, where does God give him that hope?
Does he mean "You have been the protection of your People throughout the changes of history" or "the home we go to after our troubled journey"?
