Instrumental music in worship clearly linked with Old Testament revival (an excerpt from The Biblica
After the reign of King David, periods of moral and spiritual revival in Israel’s history often included a return to the worship practices of David and the use of musical instruments in worship. As Daniel Caram points out in his book, Tabernacle of David, “The revivalists always came back to the Davidic order of worship, not the Mosaic order.”
In 726 B.C., King Hezekiah repaired the house of the Lord and restored Davidic worship:
"He then stationed the Levites in the house of the Lord with cymbals, with harps, and with lyres, according to the command of David and of Gad the king’s seer, and of Nathan the prophet; for the command was from the Lord through His prophets. And the Levites stood with the musical instruments of David, and the priests with the trumpets. Then Hezekiah gave the order to offer the burnt offering on the altar. When the burnt offering began, the song to the Lord also began with the trumpets, accompanied by the instruments of David, king of Israel. While the whole assembly worshiped, the singers also sang and the trumpets sounded; all this continued until the burnt offering was finished" (2 Chron. 29:25-28).
After the restoration of Judah from Babylon in 536 B.C., the first order of business was to rebuild the Temple, and even before it was finished, Davidic worship with musical instruments was reinstituted: "Now when the builders had laid the foundation of the temple of the Lord, the priests stood in their apparel with trumpets, and the Levites, the sons of Asaph, with cymbals, to praise the Lord according to the directions of King David of Israel" (Ezra 3:10).
Finally, when Nehemiah was successful in rebuilding the walls of Jerusalem a number of years later, the dedication ceremony included a reference to two great choirs and musicians “with the musical instruments of David the man of God” (Neh. 12:36). Kevin Conner reminds us in his book, The Tabernacle of David, “that the godly Kings of Israel who brought Israel back to the Lord always restored the order of worship that was established by David the King in the Tabernacle of David.”
