1 Chronicles 9:25-27

New Revised Standard Version, Anglicised Catholic Edition

²⁵ and their kindred who were in their villages were obliged to come in every seven days, in turn, to be with them; ²⁶ for the four chief gatekeepers, who were Levites, were in charge of the chambers and the treasures of the house of God. ²⁷ And they would spend the night near the house of God; for on them lay the duty of watching, and they had charge of opening it every morning.
