1 Chronicles 15:25–28, Old Testament, The Church of Jesus Christ of Latter-day Saints, accessed January 22, 2024
25 ¶ So David, and the elders of Israel, and the captains over thousands, went to bring up the ark of the covenant of the Lᴏʀᴅ out of the house of Obed-edom with joy.
26 And it came to pass, when God helped the Levites that bare the ark of the covenant of the Lᴏʀᴅ, that they offered seven bullocks and seven rams.
27 And David was clothed with a robe of fine linen, and all the Levites that bare the ark, and the singers, and Chenaniah the master of the song with the singers: David also had upon him an ephod of linen.
28 Thus all Israel brought up the ark of the covenant of the Lᴏʀᴅ with shouting, and with sound of the cornet, and with trumpets, and with cymbals, making a noise with psalteries and harps.
