1 Chronicles 15:22-26

Chenaniah, chief of the Levites, was in charge of the singing; he gave instruction in singing because he was skillful.

Berechiah and Elkanah were gatekeepers for the ark.

Shebaniah, Joshaphat, Nethanel, Amasai, Zechariah, Benaiah, and Eliezer, the priests, blew the trumpets before the ark of God. Obed-edom and Jehiah also were gatekeepers for the ark.

So it was David, with the elders of Israel and the captains of thousands, who went to bring up the ark of the covenant of the Lord from the house of Obed-edom with joy.

Because God was helping the Levites who were carrying the ark of the covenant of the Lord, they sacrificed seven bulls and seven rams.
