Passage
In the morning it flourisheth, and hath changed, At evening it is cut down, and hath withered.
In the morning it flourisheth, and hath changed, At evening it is cut down, and hath withered.
Psalms 90:4 For a thousand years in Thine eyes <FI>are<Fi> as yesterday, For it passeth on, yea, a watch by night.
Psalms 90:5 Thou hast inundated them, they are asleep, In the morning as grass he changeth.
Psalms 90:6 In the morning it flourisheth, and hath changed, At evening it is cut down, and hath withered.
Psalms 90:7 For we were consumed in Thine anger, And in Thy fury we have been troubled.
Psalms 90:8 Thou hast set our iniquities before Thee, Our hidden things at the light of Thy face,
The verse centers on "morning", "flourisheth", "hath", "changed", "evening", "down", and "withered". It is saying that the verse draws attention to "morning" and "flourisheth", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 5's "Thou hast inundated them they are asleep..." into verse 7's "For we were consumed in Thine anger...", so "morning" and "flourisheth" belong inside that flow. 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 "morning" and "flourisheth" with trust shaped by these words, not by a vague optimism outside the passage.
