These two verses come from the psalm of thanksgiving that David instructed Asaph and the Levite singers to sing during the procession of the Ark to its new home in Jerusalem. David was not only a good king, he was a good worship service planner.
The first stanza invites all the earth to sing to the Lord. The next instructs his saints to proclaim the gospel (“good news”) every day. The third and fourth stanzas instruct the saints to declare God’s “glory” and “wonders” among every nation and people. Reading this, one can see the continuity of David’s song and Christ’s Great Commission, namely, to “go and make disciples of all nations.”
What a wonderful worship service David planned for the Ark’s arrival in its new home! And what a worship service the Lord plans for us when we arrive home with Him!
