1 Chronicles 15:25

And Berechiah and Elkanah were doorkeepers for the ark.

And Shebaniah, and Jehoshaphat, and Nethaneel, and Amasai, and Zechariah, and Benaiah, and Eliezer, the priests, did blow with the trumpets before the ark of God: and Obededom and Jehiah were doorkeepers for the ark.

And it came to pass, when God helped the Levites that bare the ark of the covenant of the LORD, that they offered seven bullocks and seven rams.

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.
