2 Chronicles 23:3-5

Young's Literal Translation

³ and all the assembly make a covenant in the house of God with the king, and he saith to them, `Lo, the son of the king doth reign, as Jehovah spake concerning the sons of David.

⁴ `This [is] the thing that ye do: The third of you, going in on the sabbath, of the priests, and of the Levites, [are] for gatekeepers of the thresholds,

⁵ and the third [are] at the house of the king, and the third at the gate of the foundation, and all the people [are] in the courts of the house of Jehovah.
