1 Chronicles 15:22-26

And Chenaniah, chief of the Levites, was for song: he instructed about the song, because he was skilful.

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 Obed-edom and Jehiah were doorkeepers for the ark.

So David, and the elders of Israel, and the captains over thousands, went to bring up the ark of the covenant of the LORD out of the house of Obed-edom with joy.

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.
