Passage
Lord, thou hast been our dwelling-place In all generations.
Lord, thou hast been our dwelling-place In all generations.
Psalms 90:1 Lord, thou hast been our dwelling-place In all generations.
Psalms 90:2 Before the mountains were brought forth, Or ever thou hadst formed the earth and the world, Even from everlasting to everlasting, thou art God.
Psalms 90:3 Thou turnest man to destruction, And sayest, Return, ye children of men.
The verse centers on "lord", "thou", "hast", "been", "dwelling-place", and "generations". It is saying that the verse draws attention to "lord" and "thou", so its meaning should be read from those terms before moving to application.
The next verse adds "Before the mountains were brought forth Or...", so "lord" and "thou" should be read forward into that movement. In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "lord" and "thou" with trust shaped by these words, not by a vague optimism outside the passage.
