2 Chronicles 23:6-8

Young's Literal Translation

⁶ `And none doth enter the house of Jehovah except the priests, and those ministering of the Levites (they go in for they [are] holy), and all the people keep the watch of Jehovah:

⁷ and the Levites have compassed the king round about, each with his weapon in his hand, and he who hath gone in unto the house is put to death; and be ye with the king in his coming in and in his going out.'

⁸ And the Levites and all Judah do according to all that Jehoiada the priest hath commanded, and take each his men going in on the sabbath, with those going out on the sabbath, for Jehoiada the priest hath not let away the courses.
