Temple keepers or servants were subordinate workers assigned to duties connected with the tabernacle or temple. Such service included carrying wood and water and guarding or maintaining the sanctuary. The biblical notices explain the presence of a non-Israelite or otherwise subordinate class serving at holy places.
Levites received persons and animals taken after the conquest of Midian for the charge of the tabernacle. The Gibeonites were made hewers of wood and drawers of water for the congregation and altar. Ezekiel condemned the admission of uncircumcised foreigners into the sanctuary and directed that degraded Levites perform the ordinary temple duties, while the sons of Zadok offered sacrifices.
The source connects the origin of sanctuary servants with the incorporation of people from Midian and Gibeon into duties assigned to the tabernacle and altar. Ezekiel’s arrangement included a special room in the inner court for priests who kept charge of the temple.
