2 Chronicles 23:4-7

The Voice

⁴ This is what you will do: One-third of you priests and Levites who work on the Sabbath will guard the gates to the temple, ^5-7 one-third will guard Joash’s house, and one-third will guard the gate of the foundation. Those posted at the king’s house will surround him with drawn weapons. If anyone enters Joash’s house, kill him. If Joash leaves his house, kill anyone who approaches him.

All the people will wait in the courts of the Eternal’s house and guard His temple. Kill anyone who comes into the Eternal’s house (except, of course, for the priests and ministering Levites who are consecrated).
