The priests Shebaniah, Joshaphat, Nethanel, Amasai, Zechariah, Benaiah, and Eliezer had the job of blowing trumpets in front of the Ark of God. Obed-Edom and Jehiah were also guards for the Ark.
Also blow your trumpets at happy times and during your feasts and at New Moon festivals. Blow them over your burnt offerings and fellowship offerings, because they will help you remember your God. I am the Lord your God.”
