'Gatekeepers' in the Bible

The Descendants of the Gatekeepers: Descendants of Shallum, Ater, Talmon, Akkub, Hatita, and Shobai, totaling: 139

Some of the descendants of Israel also left for Jerusalem, including the priests, the descendants of Levi, the singers, the gatekeepers, and the Temple Servants, during the seventh year of King Artaxerxes.

Furthermore, we decree that with respect to any of the priests, descendants of Levi, singers, gatekeepers, Temple Servants, or other servants of this Temple of God, it is not to be lawful to impose any tribute, tax, or toll on them.

From the singers: Eliashib. From the gatekeepers: Shallum, Telem, and Uri.
