2 Chronicles 23:6-8

Amplified Bible

⁶ But let no one enter the house (temple) of the Lord except the priests and the Levites who minister; they may enter, for they are holy. And let all the people carefully observe the law of the Lord. ⁷ The Levites shall surround the [young] king, every man with his weapons in his hand; and whoever comes into the temple [breaking through the ranks of the guard to get near Joash] is to be killed. You are to be with the king when he comes in [from the temple chamber where he is hiding] and when he goes out.”

⁸ So the Levites and all Judah acted in accordance with everything that Jehoiada the priest had commanded; and every man took his men who were to resume duty on the Sabbath, with those who were to go off duty on the Sabbath, for Jehoiada the priest did not dismiss [any of] the divisions [from their duties].
