2 Kings 11:5-7

11:5 He ordered them, “This is what you must do. One third of the unit that is on duty during the Sabbath will guard the royal palace. 11:6 Another third of you will be stationed at the Foundation Gate. Still another third of you will be stationed at the gate behind the royal guard. You will take turns guarding the palace. 11:7 The two units who are off duty on the Sabbath will guard the Lord’s temple and protect the king.
