Shebaniah, Joshaphat, Nethanel, Amasai, Zechariah, Benaiah, and Eliezer, the priests, should blow the trumpets before the ark of God. Obed-edom and Jehiah were to be gatekeepers for the ark.
On the day of your gladness also, and at your appointed feasts and at the beginnings of your months, you shall blow the trumpets over your burnt offerings and over the sacrifices of your peace offerings. They shall be a reminder of you before your God: I am the Lord your God.”
