Passage
Make a joyful noise unto Jehovah, all ye lands.
Make a joyful noise unto Jehovah, all ye lands.
Psalms 100:1 Make a joyful noise unto Jehovah, all ye lands.
Psalms 100:2 Serve Jehovah with gladness: Come before his presence with singing.
Psalms 100:3 Know ye that Jehovah, he is God: It is he that hath made us, and we are his; We are his people, and the sheep of his pasture.
The verse centers on "make", "joyful", "noise", "jehovah", and "lands". It is saying that the verse draws attention to "make" and "joyful", so its meaning should be read from those terms before moving to application.
The next verse adds "Serve Jehovah with gladness Come before his...", so "make" and "joyful" 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 "make" and "joyful" with trust shaped by these words, not by a vague optimism outside the passage.
