Berechiah and Elkanah were doorkeepers for the ark.

Shebaniah, and Joshaphat, and Nethanel, and Amasai, and Zechariah, and Benaiah, and Eliezer, the priests, did blow the trumpets before the ark of God: and Obed-Edom and Jehiah were doorkeepers for the ark.

and Obed-Edom with their brothers, sixty-eight; Obed-Edom also the son of Jeduthun and Hosah to be doorkeepers;

four thousand were doorkeepers; and four thousand praised Yahweh with the instruments which I made, for giving praise."

For the divisions of the doorkeepers: of the Korahites, Meshelemiah the son of Kore, of the sons of Asaph.

Of these were the divisions of the doorkeepers, even of the chief men, having offices like their brothers, to minister in the house of Yahweh.

These were the divisions of the doorkeepers; of the sons of the Korahites, and of the sons of Merari.
