Passage
A Psalm of Thanksgiving. Make a loud shout to Yahweh, all the earth.
A Psalm of Thanksgiving. Make a loud shout to Yahweh, all the earth.
Psalms 100:1 A Psalm of Thanksgiving. Make a loud shout to Yahweh, all the earth.
Psalms 100:2 Serve Yahweh with gladness; Come before Him with joyful songs.
Psalms 100:3 Know that Yahweh, He is God; It is He who has made us, and not we ourselves; We are His people and the sheep of His pasture.
The verse centers on "psalm", "thanksgiving", "make", "loud", "shout", "yahweh", and "earth". It is saying that the verse draws attention to "psalm" and "thanksgiving", so its meaning should be read from those terms before moving to application.
The next verse adds "Serve Yahweh with gladness Come before Him...", so "psalm" and "thanksgiving" 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 "psalm" and "thanksgiving" with trust shaped by these words, not by a vague optimism outside the passage.
