1 Chronicles 15:24

And Shebaniah, and Jehoshaphat, and Nethaneel, and Amasai,
and Zechariah, and Benaiah, and Eliezer, the priests, did blow with
the trumpets before the ark of God
With the silver trumpets; one use of which was to blow with when the camps and ark of the Lord moved, ( Numbers 10:5 Numbers 10:6 ) .

and Obededom and Jehiah were doorkeepers for the ark;
they went behind it, as the others before it, for the same purpose, as it was bringing up.
