Passage
Then on that day David first ordained to give thanks to Yahweh, by the hand of Asaph and his brothers.
Then on that day David first ordained to give thanks to Yahweh, by the hand of Asaph and his brothers.
1 Chronicles 16:5 Asaph the chief, and second to him Zechariah, then Jeiel, Shemiramoth, Jehiel, Mattithiah, Eliab, Benaiah, Obed-Edom, and Jeiel, with stringed instruments and with harps; and Asaph with cymbals, sounding aloud;
1 Chronicles 16:6 with Benaiah and Jahaziel the priests with trumpets continually, before the ark of the covenant of God.
1 Chronicles 16:7 Then on that day David first ordained to give thanks to Yahweh, by the hand of Asaph and his brothers.
1 Chronicles 16:8 Oh give thanks to Yahweh. Call on his name. Make what he has done known among the peoples.
1 Chronicles 16:9 Sing to him. Sing praises to him. Tell of all his marvelous works.
The verse centers on "david", "first", "ordained", "give", "thanks", "yahweh", "hand", and "asaph". It is saying that the verse draws attention to "david" and "first", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "with Benaiah and Jahaziel the priests with..." into verse 8's "Oh give thanks to Yahweh Call on...", so "david" and "first" belong inside that flow. In 1 Chronicles context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "david" and "first" with trust shaped by these words, not by a vague optimism outside the passage.
