'Door keepers' in the Bible

The children of the door-keepers: the children of Shallum, the children of Ater, the children of Talmon, the children of Akkub, the children of Hatita, the children of Shobai, a hundred and thirty-nine.

So the priests and the Levites and the people and the music-makers and the door-keepers and the Nethinim, took up their places in their towns; even all Israel in their towns.

And some of the children of Israel went up, with some of the priests and the Levites and the music-makers and the door-keepers and the Nethinim, to Jerusalem, in the seventh year of Artaxerxes the king.

In addition, we make it clear to you, that it will be against the law to put any tax or payment in goods or forced payment on any of the priests or Levites, the music-makers, door-keepers, Nethinim, or any servants of this house of God.

And of the music-makers, Eliashib; and of the door-keepers, Shallum and Telem and Uri.
