The priests, Shebaniah, Joshaphat, Nethanel, Amasai, Zechariah, Benaiah, and Eliezer, were to blow trumpets before the ark of God. Obed-edom and Jehiah were also to be gatekeepers for the ark.
You are to sound the trumpets over your burnt offerings and your fellowship sacrifices and on your joyous occasions, your appointed festivals, and the beginning of each of your months. They will serve as a reminder for you before your God: I am the Lord your God.’
