2 Chronicles 23:3-5

New Revised Standard Version, Anglicised Catholic Edition

³ Then the whole assembly made a covenant with the king in the house of God. Jehoiada^[a] said to them, ‘Here is the king’s son! Let him reign, as the Lord promised concerning the sons of David. ⁴ This is what you are to do: one-third of you, priests and Levites, who come on duty on the sabbath, shall be gatekeepers, ⁵ one-third shall be at the king’s house, and one-third at the Gate of the Foundation; and all the people shall be in the courts of the house of the Lord.
