Passage
And let the beauty of Jehovah our God be upon us; and establish thou the work of our hands upon us: yea, the work of our hands, establish thou it.
And let the beauty of Jehovah our God be upon us; and establish thou the work of our hands upon us: yea, the work of our hands, establish thou it.
Psalms 90:15 Make us glad according to the days [wherein] thou hast afflicted us, according to the years [wherein] we have seen evil.
Psalms 90:16 Let thy work appear unto thy servants, and thy majesty unto their sons.
Psalms 90:17 And let the beauty of Jehovah our God be upon us; and establish thou the work of our hands upon us: yea, the work of our hands, establish thou it.
The verse centers on "beauty", "jehovah", "upon", "establish", "thou", and "hands". It is saying that the verse draws attention to "beauty" and "jehovah", so its meaning should be read from those terms before moving to application.
The prior verse says "Let thy work appear unto thy servants...", giving immediate footing for "beauty" and "jehovah". 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 "beauty" and "jehovah" with trust shaped by these words, not by a vague optimism outside the passage.
