1 Chronicles 15:25-28

Now they were ready. David, the elders of Israel, and the commanders of thousands started out to get the Chest of the Covenant of GOD and bring it up from the house of Obed-Edom. And they went rejoicing. Because God helped the Levites, strengthening them as they carried the Chest of the Covenant of GOD, they paused to worship by sacrificing seven bulls and seven rams. They were all dressed in elegant linen—David, the Levites carrying the Chest, the choir and band, and Kenaniah who was directing the music. David also wore a linen prayer shawl (called an ephod). On they came, all Israel on parade bringing up the Chest of the Covenant of GOD, shouting and cheering, playing every kind of brass and percussion and string instrument.
