Shebaniah, Joshaphat, Nethanel, Amasai, Zechariah, Benaiah, and Eliezer, the priests, were to blow the trumpets before the ark of God. Obed-edom and Jehiah also were to be gatekeepers for the ark.
Also on your days of rejoicing, at your appointed festivals, and at the beginnings of your months, you shall blow the trumpets over your burnt offerings and over your sacrifices of well-being; they shall serve as a reminder on your behalf before the Lord your God: I am the Lord your God.”
